Most non-removed games I'd be happy to trade for store price in csgo keys at paypal value, so a collector can just have the gift. I have no attachment to 99% of this stuff, anymore. Most gifts are certainly less than store price, as well.
Do NOT waste my time by offering other games or other gifts.
Anything priced in cash is the PAYPAL PRICE ONLY

Hello everyone!
I've never found a tool for sorting roms for home and handheld consoles while for Arcade there are plenty, so I made some batch scripts for moving roms to genre folders or for deleting them. I was inspired by this post on libretro forum, so thanks to Alexandra.
You can download the scripts here. It is hosted on Mediafire.
Inside the .zip file you will find 2 folders, each one containing 19 .bat files, one folder contains scripts for moving rom files into their genre folder and on the other folder scripts for deleting them based on the genre.
There are 19 genres. I categorized every single rom for Mega Drive/Genesis (I think) using Emuparadise and GameFAQs and a little of my preference (because some games could fit more than one genre). If you find some rom that is missing from the scripts or you think a game should be under another genre, let me know.
The 19 genre are:

• Action
• Adventure
• Beat-Em-Up
• Compilation (for roms with more than one game, except for Sonic & Knuckles + other Sonics games that are under the Platformer genre)
• Driving-Racing
• Educational
• Fighting
• First-Person (FPS and also some tank simulation)
• Flight-Simulator (including Spacecrafts)
• Light-Gun (games that uses this peripheral)
• Others (for bios, cheat devices and other peripherals like Sega Channel and MegaNet)
• Pinball
• Platformer
• Puzzle
• RPG (includes Action RPG)
• Shooter (most Vertical and Horizontal Scrolling Shoot 'em Up, I put most of Top-Down Shooters on the Action genre)
• Sports
• Strategy (includes Real Time and Tactical Turn Based)
• Trivia-Board-Casino

​
How the scripts works?
Only works on Windows.
Put all the 19 scripts for moving OR deleting on the same folder of your rom files. The rom files should follow the No-Intro naming convention, but the scripts will ignore region, revision and extension, so doesn't matter if the rom is (USA) or (USA, Japan) or (REV A) or (REV 1) or. md or .bin, as long the game name follows No-Intro naming. This should also work with Translated games that has [T+] or [T-] codes in the name.
Run each of the 19 .bat files by double clicking on it. The moving script will create a folder named after the genre and move all rom files from that genre to it, so you don't need to create the folder manually.
CAUTION: The scripts for deleting will do so permanently, that means the deleted rom files will not go to the Trash Bin.
I think some antivirus can detect the scripts as virus, but I guaranteed they don't do anything malicious. You can actually see what the script does by right clicking on it and clicking on "Edit" on the drop down menu, the NotePad will open with the codes used to run the script. You can also edit the scripts so you may manually include or exclude a game under a genre.
​
I'm planning to make those scripts for some other systems like Sega Master System, Game Gear, SNES, NES, GBA, GBC, GB, NEC-Pc Engine/Turbo Grafx... but not sure when.
I also planning to make a catver.ini file so you can use with Simple Arcade Multifilter and No-Intro datafiles
​
EXTRA: I also made a batch script to delete Barbie, Dora the Explorer, Bratz and Polly Pocket games (because yes) that works with any system rom file, just put the .bat file on the rom folder you want and run it. This script will actually prompt you before the deletion, so you can select "yes" or "no" for every game it could delete. Again caution with this because the deletion is permanent and you can easily edit it to include other games if you like.
You can download this script here.

Hi! I have compiled a big list of challenges your players can encounter during the adventure.

• These challenges can be used as sub-goals the players will need to achieve on the path to their main goal, as obstacles they need to overcome to get what they want.
• Most of them can also be used as the primary goal, an idea for the whole adventure (just make the stakes higher, make it important/interesting/exciting to accomplish, make it more difficult, add sub-goals and obstacles players need to get through to achieve it).
• Challenges can be mixed and matched. In one adventure, challenge A can be the big primary goal, and challenge B can be a step towards accomplishing this big goal. In another adventure, it can be the other way around. In one adventure, the players need to obtain an item (a powerful weapon) to slay a monster, in another, they need to slay a monster to get their hands on the valuable item. In one adventure they need to rescue someone who has a clue to the mystery, in another they need to solve a mystery to be able to rescue someone.
• Use multiple challenges together to add more depth, make the adventure more difficult/interesting, get players to fight on several fronts. Combine challenges to make them complications for each other, or use conflicting challenges that are incompatible with each other to create difficult choices. Players need to protect a person while also being on the run from the law, they need to spy on someone while traveling through the dangerous environment, they need to fight for political power while pretending to be someone they're not, they need to slay a big monster in the middle of the city while protecting people and avoiding collateral damage.

If you find this list useful - please help me to improve and extend it!

• Share more challenge ideas, how can these challenge lists can be extended?
• What other big challenge categories could I add? Please share a few challenge examples in those categories.
• Share interesting examples for each kind of challenge.
• Share interesting complications and combinations of challenges.
• Share feedback/advice/ideas on improving this project.
• Share good resources (books, random tables, articles) I can use to extend this list.

• Do it while competing with the rival team.
• Unrelated people are interfering with the objective.
• Do it stealthily (don't attract attention, don't leave clues, no witnesses).
• Do it while pretending to be someone else.
• Do it without revealing that your client is involved.
• Prevent collateral damage, protect the innocents who are around.

Edit:
I've had a few pretty huge epiphanies while writing this post:

• Stories are fundamentally about problem solving. Roleplaying is fundamentally about problem solving. This is the fundamental "game loop" of RPGs - GM puts a problem in front of the players, and they find creative ways to solve it, that's what gives them fun stuff to do and feels satisfying to accomplish.
• Adventure Ideas are fundamentally problems. They create an exciting, challenging, important goal for the players to accomplish.
• Big problems are broken down into small challenges. But fundamentally, the big climactic adventure/campaign goals and the small challenges players encounter on their way are the same thing. Every scene the characters solve a small problem, and it drives them towards solving the big problem. That's what plot points are - players solving or failing to solve a problem, which moves them closer to or farther away from the goal. Which feels exciting/valuable/dramatic.
• Conflict, obstacles, social/exploration/combat encounters are fundamentally just sources of problems. There probably are other sources that can generate problems.
• It's all just nested challenges: Campaign Problem > Adventure Problem > Scene Problem. And any challenge can be used on any of these levels.
• Therefore, the list above is a list of adventure ideas and plot points at the same time. Make any challenge very important/difficult/exciting to accomplish - and it becomes an idea for the adventure or a campaign. Make any adventure idea relatively small and simple - and it becomes a scene challenge (encounter). Put a number of smaller challenges in front of the players - and you've got your basic story structure (a list of encounters, the gameplay). Because goals and challenges are fundamentally the same, just the nested problems, they can be combined in any order to create any number of unique adventures.
• Also, it means that you can take big story ideas from movies, TV episodes, published modules, and use them as ideas for small encounters. Shawshank Redemption, Alien, Jaws, Incredibles - they can be big campaign ideas, small adventure ideas, or just a thing characters do in a scene (escape from the prison, hide from a monster, defeat a big golem).
• Game mechanics are also challenges. If there's an RPG system that gets players to do something awesome (GM moves in Dungeon World, Favors/Debts and Social Status mechanics from the Undying, Weak Moves from Dream Askew) - you can use those as challenges too.
• Even a single challenge can create an unlimited number of unique stories - you just change the concrete details. McGuffins, NPCs, locations, etc.

Wow, this is taking off. If you like this post, you will probably enjoy my posts on Adventure Writing Process, Adventure Template (a list of the most important questions to answer when designing an adventure), and Making Combat Awesome. If you want updates on my future posts - follow me here.

Created a little "Story Generator App" that will pick the random challenges for you.

• Difficult choice. Choose lesser of two evils, choose which people to rescue. Requiring personal sacrifice, risk, compromise.

• Only a bad/unpleasant person can provide the item/information/favor you need.
  

Using Challenges to create Adventures

• These challenges can be used as sub-goals the players will need to achieve on the path to their main goal, as obstacles they need to overcome to get what they want.
• Most of them can also be used as the primary goal, an idea for the whole adventure (just make the stakes higher, make it important/interesting/exciting to accomplish, make it more difficult, add sub-goals and obstacles players need to get through to achieve it).
• Challenges can be mixed and matched. In one adventure, challenge A can be the big primary goal, and challenge B can be a step towards accomplishing this big goal. In another adventure, it can be the other way around. In one adventure, the players need to obtain an item (a powerful weapon) to slay a monster, in another, they need to slay a monster to get their hands on the valuable item. In one adventure they need to rescue someone who has a clue to the mystery, in another they need to solve a mystery to be able to rescue someone.
• Use multiple challenges together to add more depth, make the adventure more difficult/interesting, get players to fight on several fronts. Combine challenges to make them complications for each other, or use conflicting challenges that are incompatible with each other to create difficult choices. Players need to protect a person while also being on the run from the law, they need to spy on someone while traveling through the dangerous environment, they need to fight for political power while pretending to be someone they're not, they need to slay a big monster in the middle of the city while protecting people and avoiding collateral damage.

This works because:

I recently bought a penthouse so i could do the Ms. Baker's Missions to unlock the security intel prep for casino heist.
I was doing the pre-last mission with my friend and when we were over we both joined different sessions + i was absolutely somewhere else than where i was supposed to spawn (in front of casino)
I took my oppresor mk2 and flew to the casino so i could launch the last mission. There we have our idiot.
He was in his avenger, auto-piloting over highway. I thought nothing of it. As soon as i landed he shot me dead. I asked him why he did it. He didnt answer but only killed me for the second time. I went ghosted and destroyed his avenger with RPG
Idiot: glitcher cheater noob
Me: what?? I went ghosted, i am not a cheater
Idiot: glitch exploiter loser
Me: i activated ghosted because you kept killing me. Thats what its made for.
Idiot: i reported you for glitching cheating (i dont even know what that means)
Me: i literally did nothing, i was not in passive, i went ghosted
(mind you this guy was rank 338 and he DID NOT know the difference between ghosted and passive)
Idiot: you were in passive mode and you kept shooting while i couldnt shoot you
Me: once again i was not in passive, i went ghosted. There is a difference between those two. Passive doesnt allow you weapons at all. You can activate ghosted after someone kills you multiple times in a row. You can kill him but he cant kill you
Random person #1: [my gta username] is right, ghosted is different than passive
Random person #2: youre rank 338 and you have never before heard about ghosted??
Idiot: when i am in passive i cant use weapons. He was in passive and he could still use weapons. He is cheating and exploiting glitches
Random person #1: he was ghosted, not passive
console: players are voting to kick you out of this session. Consider improving your behaviour.
Me: did you votekick me??
Idiot: yes
Me: to sum this up: you started attacking me and i went ghosted. Then i killed you and now youre mad at me?? Youre not alright in the head, get some help for your own good
Idiot: [my gta username] noob, loser, cheater
Me: whatever, i have to go now, have fun

Edit:
I've had a few pretty huge epiphanies while writing this post:

• Stories are fundamentally about problem solving. Roleplaying is fundamentally about problem solving. This is the fundamental "game loop" of RPGs - GM puts a problem in front of the players, and they find creative ways to solve it, that's what gives them fun stuff to do and feels satisfying to accomplish.
• Adventure Ideas are fundamentally problems. They create an exciting, challenging, important goal for the players to accomplish.
• Big problems are broken down into small challenges. But fundamentally, the big climactic adventure/campaign goals and the small challenges players encounter on their way are the same thing. Every scene the characters solve a small problem, and it drives them towards solving the big problem. That's what plot points are - players solving or failing to solve a problem, which moves them closer to or farther away from the goal. Which feels exciting/valuable/dramatic.
• Conflict, obstacles, social/exploration/combat encounters are fundamentally just sources of problems. There probably are other sources that can generate problems.
• It's all just nested challenges: Campaign Problem > Adventure Problem > Scene Problem. And any challenge can be used on any of these levels.
• Therefore, the list above is a list of adventure ideas and plot points at the same time. Make any challenge very important/difficult/exciting to accomplish - and it becomes an idea for the adventure or a campaign. Make any adventure idea relatively small and simple - and it becomes a scene challenge (encounter). Put a number of smaller challenges in front of the players - and you've got your basic story structure (a list of encounters, the gameplay). Because goals and challenges are fundamentally the same, just the nested problems, they can be combined in any order to create any number of unique adventures.
• Also, it means that you can take big story ideas from movies, TV episodes, published modules, and use them as ideas for small encounters. Shawshank Redemption, Alien, Jaws, Incredibles - they can be big campaign ideas, small adventure ideas, or just a thing characters do in a scene (escape from the prison, hide from a monster, defeat a big golem).
• Game mechanics are also challenges. If there's an RPG system that gets players to do something awesome (GM moves in Dungeon World, Favors/Debts and Social Status mechanics from the Undying, Weak Moves from Dream Askew) - you can use those as challenges too.
• Even a single challenge can create an unlimited number of unique stories - you just change the concrete details. McGuffins, NPCs, locations, etc.

Use the Adventure Writing Template to help you develop these challenges into a complete adventure.
I have also made an "Adventure Prompts Tool" that will pick the random challenges for you (it also contains some prompts for settings and villains).
Also see the Big List of Adventure Ideas - the list of challenges that will work well as the main idea for the adventure (a goal for the Players or the Villain).
