    The source code is floating around the ‘net and readily available, and it looks likes it’s a GPL v.2 license, so it seems like it would be a no-brainer to include. The 7800 is another 6502-based system, a technological contemporary of the NES. ProSystem is part of the OpenEmu system for OS X and I’d love to see it part of RetroPie. Surely I can’t be the only one who’d like some 7800 action on our Pi’s.

    Is this the source to which you refer?

    Supposedly this dude compiled it to work on the Raspberry Pi:

    Wish I knew more about porting/compiling

    Well, the code I’m referring to is here – it hasn’t been updated in over 6 years but it’s still archived and downloadable, and it functions quite well (at least the version compiled to run in OpemEmu under OS X does).

    http://www.zophar.net/a7800/prosystem.html

    I downloaded a copy myself so I know the link is still alive/working. I haven’t seen that thread at AtariAge but I’ll check it out, thanks!

    There is a libretro core – it didn’t work before though. There have been some changes since then so im testing now and if it works, I’ll include it.

    I have added it to experimental section. Please let me know how it works for you. You can “optionally” install “7800 BIOS (U).rom” – works without but you don’t get the atari logo then

    tested a bunch of games and they all work perfect. Minus barnyard blaster mainly because I don’t own a light gun. Thanks Buzz!

    The NTSC BIOS worked being named “7800 BIOS (U).rom” and placed in the BIOS folder but the PAL BIOS didn’t seem to work. I tried “7800 BIOS (E).rom” as well as “7800pal.rom” in both the BIOS and the ROM folder but it seemed that the PAL BIOS wouldn’t load either way. Maybe I just had it named wrong or in the wrong place. It’s not really a big deal as it isn’t a necessary thing but just a heads up if anyone else tries pal roms with the NTSC BIOS enabled- it won’t work.

    Works pretty well, thanks, complete with rainbow Atari boot screen. I tried one ROM just as a test (Xevious) – I noticed some tearing in the vertical scrolling as compared to my real 7800 and cartridge, but that may be an artifact of playing on a bigger LCD (I usually play on a 13″ CRT). The colors appear kind of bright and washed out, as if the gamma is too high, but I’ll fool around with configuration options and see if I can tweak that.

    Thanks!!!

    Seroiously? That’s great news!
    I have it working under AdvMESS from the command line, the colors are a bit wrong, and I can not figure how to run it in Emulation Station, and every thread with this problem dies without a solution.

    Are you running .bin or .a78, or do both work?

    I know you didn’t reply to me, but I tested a Xevious rom in .a78 and it plays great.

    As you and I both noted, the colors appear off, in my case too bright as if gamma is too high. Probably something configurable somewhere. I intend to dig into it tomorrow.

    Try this homebrew.
    Probably the inspiration for Activision’s Megamania.
    I used to hate it in the arcade because of its difficulty and it didn’t give much play per quarter.
    Now I can’t stop playing!

    That game is pretty alright for a homebrew

    The 7800 has an incredibly vibrant homebrew scene, and a lot of them end up being placed on carts and sold at retail to retro-hobbyists. Anything by Bob DeCredenso (sp?) is worth looking at! Most of the homebrew 7800 ROMS can be found on AA – the developers usually make them (or very late beta versions) available for download and play testing. Sometimes they release final versions a few months after the carts go on sale just because they want to give back to the gaming community. I have a slew of them – I highly recommend Beef Drop (an excellent Burger Time port) and Asteroids Deluxe, among many others.

    Now I just gotta find the config settings to get my X-Arcade Tankstick to work properly …

    OMG you guys kick ass! 7800 is working nicely here.

    One thing that happened to me during the install though, was that my es_systems.cfg file got wiped out. (I’ve had trouble with the file before, I think because I have some systems commented out.) I had a copy on my desktop so recovery was simple. So definitely make a backup first. 😉

    …now I just need to get a colecovision emulator working.

    There is an sdl verion of adamem for colecovision, but the 1.8.1 version I have found references to has no source.

    If someone can get hold of the source for this, we could take a look. or if any other sdl emulator is found.

    This might be worth looking into for colecovision though it seems the author is a little more restrictive about his code.

    I’ve also added the 7800 to the wiki

    but it is not in the beta 2 release or in the testing downloads, either.

    edit: disregard. I found the answer in a different thread.
