This is not a ROM/game sharing site - https://retropie.org.uk/forum/topic/2/forum-rules. That being said, there's a handy topic that it might be of help - https://retropie.org.uk/forum/topic/10918/where-to-legally-acquire-content-to-play-on-retropie.

@Tackskull .ecm files are not supported by the emulator, you need to convert them to .bin - https://visihow.com/Decompress_PlayStation_1_Games_from_ECM_to_BIN_Using_UnECM

@kingfrankbob Welcome to the club. 😎

@DamianGerard I think you are more confused than you realize...

@Rick22 Gamegator does not sell the keys, it just lists and links to other sites. I don't trust most of these sites and don't recommend them, but this is just my personal opinion. I used some other places (pointing to same resellers anyway). As I pay with PayPal, there are some additional fees, plus taxes. I probably have used such sites 10 times and 2 times games was removed from my Steam account after several month with a message, that these were illegal keys. Since then I only use sources which are apparently legal.

On pc definitely Quake 3 threewave capture the flag. or capturestrike. On Retropie. Gotta say its Kid Chamelon or Mario 3 which is my wifes fav heh

@AndersHP You mean without emulation? Do you want run the games on your Raspberry Pie or an PC using RetroPie? Games build for PC are usually build for the x86 compatible Intel processors and the Raspberry Pie isn't compatible with them. If you want run PC games on your RPi, then you need to re-encode (means compile or build) for that system. That only works with the source code available and only if someone ports it by changing the code. If I understood your question wrong, then sorry. Can you clear it up a bit, if I am wrong?

@tpo1990 Shame jazz 2 will be more then nice !!! will love it ;) The bonus leve's dont work right at all...(no road all the screen is BLACK u cant see anything beside JAZZ & DIAMONDS).

@m2306 Lag really doesn't have to be an issue, but it can be with the wrong hdtv. On mine I can't notice any input lag. Maybe I would be able to notice it if I could play the game side by side, crt tv vs hdtv, but it's all good for me the way I've got it set up right now.

There is a thread with a collection of sources for legal roms. It shows up as the fourth hit if you search the forum for "legal roms". https://retropie.org.uk/forum/topic/10918/where-to-legally-acquire-content-to-play-on-retropie

I used the automatic way of doing it by just making the retropie-mount folder in the root of the drive and plugging it in to the pi and just let it do its thing. Thanks.

@joshuaquinn Adding to @rbaker's reply, once you have your game created, you would add it to RetroPie as a Port.

I'm sorry I don't have the actual names for the games readily available, but my Attract Mode Advance Mame Trackball romlist is as follows: #Name;Title;Emulator;CloneOf;Year;Manufacturer;Category;Players;Rotation;Control;Status;DisplayCount;DisplayType;AltRomname;AltTitle;Extra;Buttons abaseb;abaseb;MAME (Advance);;;;;;;;;;;;; amerdart;amerdart;MAME (Advance);;;;;;;;;;;;; arcadecl;arcadecl;MAME (Advance);;;;;;;;;;;;; atarifb;atarifb;MAME (Advance);;;;;;;;;;;;; soccer;soccer;MAME (Advance);;;;;;;;;;;;; bigevglf;bigevglf;MAME (Advance);;;;;;;;;;;;; bking;bking;MAME (Advance);;;;;;;;;;;;; bking2;bking2;MAME (Advance);;;;;;;;;;;;; bking3;bking3;MAME (Advance);;;;;;;;;;;;; bladestl;bladestl;MAME (Advance);;;;;;;;;;;;; bootcamp;bootcamp;MAME (Advance);;;;;;;;;;;;; bowlrama;bowlrama;MAME (Advance);;;;;;;;;;;;; bowler;bowler;MAME (Advance);;;;;;;;;;;;; bullsdrt;bullsdrt;MAME (Advance);;;;;;;;;;;;; cabal;cabal;MAME (Advance);;1988;Fabtek;Action / Fighting / Shooter;2;;;;;;;; capbowl;capbowl;MAME (Advance);;;;;;;;;;;;; caterplr;caterplr;MAME (Advance);;;;;;;;;;;;; centiped;Centipede;MAME (Advance);;;;;;;;;;;;; champbwl;champbwl;MAME (Advance);;;;;;;;;;;;; combasc;combasc;MAME (Advance);;;;;;;;;;;;; coolpool;coolpool;MAME (Advance);;;;;;;;;;;;; clbowl;clbowl;MAME (Advance);;;;;;;;;;;;; ccastles;ccastles;MAME (Advance);;;;;;;;;;;;; eaglshot;eaglshot;MAME (Advance);;;;;;;;;;;;; ebases;ebases;MAME (Advance);;;;;;;;;;;;; gimeabrk;gimeabrk;MAME (Advance);;;;;;;;;;;;; gghost;gghost;MAME (Advance);;;;;;;;;;;;; gridiron;gridiron;MAME (Advance);;;;;;;;;;;;; gt2k;gt2k;MAME (Advance);;;;;;;;;;;;; gt3d;gt3d;MAME (Advance);;;;;;;;;;;;; gt97;gt97;MAME (Advance);;;;;;;;;;;;; gt99;gt99;MAME (Advance);;;;;;;;;;;;; gtclassc;gtclassc;MAME (Advance);;;;;;;;;;;;; gtg2;gtg2;MAME (Advance);;;;;;;;;;;;; krzybowl;krzybowl;MAME (Advance);;;;;;;;;;;;; liberatr;liberatr;MAME (Advance);;;;;;;;;;;;; magworm;magworm;MAME (Advance);;;;;;;;;;;;; marble;Marble Madness;MAME (Advance);;;;;;;;;;;;; mhavoc;mhavoc;MAME (Advance);;;;;;;;;;;;; milliped;milliped;MAME (Advance);;;;;;;;;;;;; minigolf;minigolf;MAME (Advance);;;;;;;;;;;;; missile;Missile Command - Set 1;MAME (Advance);;;;;;;;;;;;; missile2;Missile Command - Set 2;MAME (Advance);;;;;;;;;;;;; poundfor;poundfor;MAME (Advance);;;;;;;;;;;;; quantum;quantum;MAME (Advance);;;;;;;;;;;;; rambo3;rambo3;MAME (Advance);;;;;;;;;;;;; rampart;rampart;MAME (Advance);;1990;Tengen;;;;;;;;;; reactor;reactor;MAME (Advance);;;;;;;;;;;;; shootbul;shootbul;MAME (Advance);;;;;;;;;;;;; sonic;sonic;MAME (Advance);;;;;;;;;;;;; shufshot;shufshot;MAME (Advance);;;;;;;;;;;;; shuuz;shuuz;MAME (Advance);;;;;;;;;;;;; simpbowl;simpbowl;MAME (Advance);;;;;;;;;;;;; slither;slither;MAME (Advance);;;;;;;;;;;;; snakepit;snakepit;MAME (Advance);;;;;;;;;;;;; spiker;spiker;MAME (Advance);;;;;;;;;;;;; stratab;stratab;MAME (Advance);;;;;;;;;;;;; sbowling;sbowling;MAME (Advance);;;;;;;;;;;;; suprleag;suprleag;MAME (Advance);;;;;;;;;;;;; syvalion;syvalion;MAME (Advance);;;;;;;;;;;;; teedoff;teedoff;MAME (Advance);;;;;;;;;;;;; tehkanwc;tehkanwc;MAME (Advance);;;;;;;;;;;;; tempest;Tempest - Vertical - Cocktail (rev 3, Revised Hardware);Cocktail;;1980;Atari;Shooter / Gallery;;;;;;;;;; tempest;Tempest - Horizontal;MAME (Advance);;1981;Atari;Shooter;1;;;;;;;; temptube;Tempest Tubes - Horizontal;MAME (Advance);;;;;;;;;;;;; temptube;Tempest Tubes - Vertical - Cocktail;Cocktail;tempest;1980;hack (Duncan Brown);;2;;dial,dial;good;1;vector;tempest;;; trisport;trisport;MAME (Advance);;;;;;;;;;;;; usclssic;usclssic;MAME (Advance);;;;;;;;;;;;; wacko;wacko;MAME (Advance);;1983;Midway;Action;2;;;;;;;; wcbowl;wcbowl;MAME (Advance);;;;;;;;;;;;; wcbowldx;wcbowldx;MAME (Advance);;;;;;;;;;;;; xtheball;xtheball;MAME (Advance);;;;;;;;;;;;; I should say this list includes several spinner/dial games that work fine using a trackball eg Tempest Tubes.

This reminds me of another hidden gem in there (already). Infectionator Survivors. Action RPG fighting zombies and finding other survivors to add to your party. You can craft weapons and healing items from junk found in the wasteland, and find weapon emplacements and other bonuses in building you clear of zombies. Also a VERY DIFFICULT game, and I love those... EDIT: After reading the article, I wonder if their new launcher CAN be ran on the Pi? I might need to take another crack at that.

@BiZzAr721 @darknior I know, such a shame not to integrate it I think it would be easily possible of the official ones from chronocrash would take part and ... i don't understand the Retropie Team ... would support a legal "RetroPie branch". I think our moderators are aware of rising support that is needed for this and indeed I can't support it because if something will fail (hardware support or whatever) on our Raspberry we are stuck and the only one who can provide better support ( @zanac ) is missing since end of 2018. Moreover OpenBOR is totally underated between other platforms so there is less awareness - but this is only my opinion. Can we update our OpenBOR from the last source code like any emulator from Retropie ? Yes with the scriptmodule but therefore I need to patch the files and upload them to my git. So we have a 6512-dev from Oct 2018 as latetst version on our Pie. I will make a new patch if the 6512 is out of dev state. Sorry for the stupid question but i break my right hand in January and stop a lot to work on computer :( Oh dear ... hope you are well. But take this is chance work on your left hand. It's not a problem to even write with the left hand. Just a bit of training ;) And... then you can also get in touch with 8bit mashines like, Commodore, Sinclair, Amstrad because you only need direction and one button -> Flightstick joypad ;)

@spyork i have encarta running in windows 3.1 in dosbox on the pi. I believe it is the “designed for wondows 95” version

Such a poor excuse for breaking the rules. There's no support for scammers here.

@hydro In short, no. The systems are too different.
