  1. I don't even know what the analog knobs did. The slot-based higher-quality ComputerEyes/2 is working in current Github, it can do double-hi-res dithered grayscale from 8 levels. That was more challenging because it actually needs to see an NTSC frame with correct H and Vsync timing.
  2. You feed it a PNG of any size and bit depth, MAME presents it to the ComputerEyes at the resolution it's expecting, and the ComputerEyes software samples it at 4 gray levels and applies dithering.
  3. MAME has a very powerful debugger, and you can write Lua scripts for it to control the emulated machine (a bot that auto-plays Karateka, for instance). You can ignore the software lists if you don't understand them and just run arbitrary disk images, like hoserama99 says. Or you can grab a software list torrent and have everything 4AM's ever released at your fingertips. Plus the only Rev. C SCSI Card emulation in existence, and it can even boot an .ISO of the Golden Orchard CD-ROM. And the next version will have ComputerEyes, JoyPort, and 4Play support plus fixes for 3200 color programs on the IIgs, and a complete set of hooks to embed MAME inside an external frontend, so the MAME interface goes completely away and you get (with the example we're shipping) something that looks a lot like VICE. 800K .WOZ and SuperDrive support are coming later this year.
  4. Are programming details available on how the Vectrex sees these spinners? We can certainly get support for them into MAME if so.
  5. It's not a subtle change depending on color profiles and all that like the NES palettes people like to argue over. We're talking about going from an EGA-style pure R, no G, no B to a more muted pink tone. It's actually even obvious if you run on a monochrome monitor, due to the luminance change. MAME has averaged between 10 and 20 source code commits every day for the 15 years since the version being run on the Pi was made. If you want to believe that none of those are user-visible, you can. Keatah noted that Tempest on the Pi version will have obvious incorrect behavior resulting in a lock up every time, the same is true of dozens of other games. It used to not be possible to get to the kill screen in Pac-Man. Operation Wolf used to be missing entire boss fights - that was just fixed last week in 0.176. And so on and so forth. Whatever your window is for games that you consider vital, they're better (and there's many more of them) after 15 more years of development on the emulation. And you wouldn't need to pay for your Mac, since you already own it. Just add fun.
  6. Easy. If the girders in DK are bright red, it's 16 year old MAME on the Pi (or a Pentium II Celeron system, which has about the same level of CPU capability). If they're more of a rose/pink, it's current MAME or a real PCB. Audio and controller latency are lower on modern builds. This isn't a case of MP3 vs MP4 or something, there are real tells present. I can't necessarily beat it for $65 (the ODROID-C2 probably will, but we don't have benchmarks yet), but the PC or Mac or Linux system or Android device you're probably typing this on all can deliver a better MAME experience for free.
  7. It's too bad he didn't clone the PCPI AppliCard instead; rather than share RAM with the 6502 and slow both CPUs down it had its own 64K on the card and the Z80 ran at 6 MHz, no wait states. And it works unmodified in the ///. But it is fun to compare how small his card is to a real original MS SoftCard. Technology's come a long way.
  8. There were some issues with the mouse on the Mac from 0.172 to 0.175, but I'm not aware of anything on Windows / MAMEUI.
  9. This is a common misconception. You very much get what you pay for: primitive emulations of games from a 16 years ago version of MAME with incorrect colors, sounds, gameplay speeds, and the occasional CPU core bug to keep things interesting. Even the golden oldies like Pacman and Donkey Kong are emulated to a far higher standard of fidelity now than was possible back then. Get a small form factor Core i5 or i7, run current MAME with a good frontend, and the experience (and game selection) is miles better.
  10. And the way you accomplish that is to have multiple folders in your ROM path. It's a path, just like a Unix or Windows $PATH, it can have multiple folders.
  11. Hahaha. It's theoretically possible to back port those games, but if you're running a device so underpowered in 2016 that you need 0.34 none of them will run well. Stop being cheap and buy a nice BRIX or NUC with a Core i7 and run real MAME 0.176.

    Excellent. I'll add complete SuperSprite support to the next MAME (including the speech and AY-3-8912).
  13. There have been several improvements in Tempest emulation over time; it contains copy protection which wasn't properly supported until fairly recently. This would cause the game to reset at random during red levels, and it was finally completely fixed in 0.153. Newer versions also can use your video card to pretty up the vectors, although nothing's quite like a real X-Y display.
  14. That version is coming up on 15 years old; if you insist on running software that old, your best bet is probably to keep around an old computer running XP. PS: MAME runs Golden Tee Fore! now. You're missing out
  15. So, Prosystem, you care to point us to any titles that supported the ALF? All I could find to test the emulation was the actual ALF music player disks that the Apple II Documentation Project has.
