Isn't N-Gage also possible? And game.com?

(And I don't know what "things aren't red enough" means. I assume that that's a play on words based on the Virtual Boy being red but you are not literally saying that Virtual Boy is impossible because of color.)

Atari 800: Artifacting support

Neo Geo: Requires a weird ROM format

Also there really should be a way to get vector games to run in higher resolutions.

If a byte-swapped BIOS is required, and not using it breaks some games, how is it possible that it works with anything at all? Wouldn't trying to execute code that's been incorrectly byte swapped execute garbage, and therefore break all games, not just some games? How could you even get a CD menu if you try to use an incorrectly byte swapped BIOS?

If it's not a legal issue, then we should think about whether the not-legal issue is something that deserves respect. I think that while we should usually respect not-legal requests, we don't need to do so all the time; some kinds of requests amount to just being a jerk, and we don't need to respect those. (Imagine software which couldn't be used b...

People got all upset about anyone raising copyright issues in that thread, but it was OP who felt the need to make this statement that the core was under a restrictive license. And it turns out such a copyright may not even be legally binding on electronics schematics, it's probably just public domain at this point. In that case it wouldn't matter...

Based on the Discord chat, the correct bios is one with a sha1 checksum of 0x829c00c3114f25b3dae5157c0a238b52a3ac37db. In Tosec 2012 this is "Goldstar FC-200 MSX Disk Basic (198x)(Goldstart).rom. On msx2.org it is there at least four separate times, under the names 8020-00bios.rom, fc200bios.com, vg8020_basic-bios1.rom, and spc800bios.rom. Che...

1.9 also works. The problem seems to be specific to 2.1.

It turns out that ctmouse 1.9.1 and 2.0 alpha 4 work. It's the 2.1 beta 4 specifically which doesn't work.

The post I based my config.sys on (with obvious changes) specifically mentions using ctmouse.

What do I need to do to get ctmouse to work? My config.sys is based on one from this thread: FILES=40 BUFFERS = 30 DOS = HIGH, UMB DEVICE=C:\USE!UMBS.SYS A000-B000 D000-EC00 DEVICE=C:\DOSMAX\DOSMAX.EXE /R+ /N+ /P- DEVICEHIGH=C:\LTEMM.EXE /p:C000 /x DEVICEHIGH=C:\FREEDOS\NANSI.SYS SHELL=C:\DOSMAX\SHELLMAX.COM C:\COMMAND.COM C:\ /E:256 /P All the pro...

I'd like to see a list of any games that won't fit either the PCXT or the ao486 cores. It will probably be a very small list and we might find workarounds to make the games work in existing cores. I tried to unzip a zip file in ao486. The unzip I could find was compiled with DJGPP and hung with a known problem . It's not a game, but it is somethin...

Would it be possible to use the 386 from the FM Towns to make a regular 386 PC core? Would it take enough less space than ao486, and/or have different bugs than ao486, for it to be useful?

On the PC Engine, some games don't work on some CD bios versions, notoriously Altered Beast and the Games Express games.

Trying freedos unzip or p7zip resulted in the problem described here; the program just hung. Obviously I can always unzip outside it, but is there any way to unzip inside it?

If anyone's wondering, I did solve my problem. The emulator image does work. Apparently "firmware" is not actually firmware. And it doesn't automatically install the core, so you can use it. The version I tried does not claim to have a mismatched core; I don't know if other versions would. Copying files in Linux is harder to find out how ...

I'm an American who's never had a real Spectrum and am confused by this: Since the .vhd cannot be written, does that mean there is no way to, for instance, save BASIC programs, or save games that have save game features, unless I use a secondary SD? There's a Spectrum Next distro at https://www.specnext.com/latestdistro/. I assume that I want to us...

As a non-FPGA pseudo-core, like SCUMMVM.

You don't need any additions for OPL3. ScummVM already has OPL3 emulation. This is something I was just trying because I got a new toy... Keep in mind, the OPL3 currently used in ao486 is in fact an emulator itself running on a NextZ80 CPU, however, It would offload some of the processing from the ARM CPU... What about the midi? Could a midi synth...

Voodoo graphics in ao486?

Would it be possible to use the FPGA for the OPL3 sound chip and the MIDI synthesizer, so SCUMMVM wouldn't need such addons?

I found that the existing scripts didn't work on actual Linux, because of the difference between "bin" and "BIN".

Wait a minute, ao486 is supposed to be a non-SDRAM core? I would have thought that as something that pushes the system to its limit it would be permitted to use SDRAM.

I was talking about things like the thread on "AdLib Emulation - Missing Percussion?" which implies that the problem won't be fixed. I could swear there was a VGA bug which wasn't going to be fixed either, but I can't find the reference.

aberu wrote: ↑Mon Jul 25, 2022 5:51 pm It's extremely difficult to work on that core,

Is this also true for video or sound problems in ao486 that don't affect the main CPU? So we should expect progress to be slow on those too?

I wanted to report back that I finally worked through the serdrive disk "Bad Command Checksum" that I have been plagued with from the start of this project. What exactly does this mean? Do the other programs used to create the drive image not create a valid drive image? Do they create valid images but sedrdrive doesn't understand certain...

Bumping old thread. I went to https://c64.ch/productions/demos/toprated and tried a few (in PAL). Biba 2 worked, but figuring out how to load this one was arcane. Deus Ex Machina crashes past the title screen if you have two disk drives. Dutch Breeze locked up after the BML screen (and pressing space) and does not show the cow screen from the scree...

I suggest C64 DTV graphics modes support. It was an actual thing you could buy in a store and hack, and people wrote programs for it that are available in the wild.

I found the problem. In this game, you cannot thrust and move at the same time. If you use a joypad, sooner or later you're going to move your finger in a direction that is not exactly up or down, and this will cause your ship to stop moving. Most games will not stop moving if you do this. So I'd either need a joystick that doesn't have diagonals, ...

I've had situations where I held the joystick in a direction (up or down) and the ship didn't move. Letting go for a second and then pressing the same direction again caused the ship to start moving. I tried Zelda on the NES with the same joystick and this *never* happened (even though Zelda is also a game which stops moving when you stop holding d...

After some struggles which I won't get into here, I got this to work and played Parsec. First of all, the joystick seems to stick a lot. Is this something in the game triggered by using too much fuel or moving it too much or something? The joystick works fine in other systems, it only seems to stick here. Also, what should I use for voice? Gogling ...
