This looks really snappy and nice. Have you tried any MIDI or other music software?

Does the 32X use QSound like the CPS2?

I have some DOS and early Windows games that use CD Audio, so I agree that this would be a useful feature.

With more demand, wouldn't it make more business sense to ramp up production and keep the price as is or lower it?

Personally I would love to see:

Wonderswan
A synthesizer core (DX7, TG100, MT-32, Sound Canvas, etc)
Jotego's X68000 core

Before we talk about MPEG-2/DVD video, what about MPEG-1? The PS1 has hardware support for MPEG-1 video, so perhaps a software developer could whip up a video player for the PS1? That video player could then be used after Laxer3a's PS1 core has been released. Another option could be to simply play videos inside Windows 95 with the ao486 core. The q...

Did you try disabling the joystick in the core settings? If it's enabled in the settings, then I think that yes, a joystick will be assigned even if you didn't connect one. To me this makes sense since it allows controllers to be hotswappable.

It works fine with just the primary SD card now (or a USB drive which I'm using). The core uses HDD images in .hdf format, as well as floppy images in .d88 format.

@akeley Yep. I got a couple of PC's with MS-DOS and Windows 9x as well. The only issues on my end with DOS games are the speed-sensitive games and games that require specific hardware (in particular, ISA sound cards). - There isn't likely to be a HUGE performance improvement in any respect beyond this, so even if performance was _doubled_ somehow f...

Problem is, pretty much ALL of these games run inferior to DOSBox, same deal with running on original hardware. Its just not as good as having an emulator that takes care of issues these systems had. ScummVM is another example... making the game run with no load times, no stuttering or anything. If you want the game to run at its best performance,...

Any idea how to "downscale" the picture in order to apply the scanlines filters to the 240p pictures ? You would have to add some code to the filter you are using, to make the filter downscale the image before it begins upscaling. If you're using the MiSTer with a CRT TV, there are some hardware-based downscalers as well, like the Mimo G...

Is the CPU really the only major component that is still missing in Laxer3a's core right now? Very exciting stuff.

Nope. Analogue's fpga cores are closed-source, so they can't be ported over to the MiSTer.

Has anyone tried Tomb Raider? I thought it might be a good performance test for the core. It did launch for me when I tried, but I couldn't get into actual gameplay. This was with cache_14 I believe, so it might get further now.

@mahen: On a PC, on real hardware, low resolutions like 320x240 will usually (always?) be scandoubled to resolutions like 640x480 before they even reach the monitor. It's always an integer scale, so good-looking scanlines are possible. But the scanline filter would have to omit every other horizontal line, or downscale the image before applying the...

Ah, that does sound like a bug/regression then.

I am aware that there are ways to bypass the hardware check, but I figured it was put there for a reason and haven't messed with it much. I also have a preinstalled HDD image of Windows 98 SE which has always had trouble booting in ao486. I admit that I haven't tried earlier releases of Windows 98 though. Did Win98 4.10.1998 work in ao486 before th...

I fired up the Windows 98 SE installer earlier today and it complains about the lack of an FPU. So this is likely not a bug, but rather missing functionality in the CPU.

I had a quick read at Wikipedia about the hardware specs: https://en.wikipedia.org/wiki/GP32#Hardware About the CPU, it says: "Samsung S3C2400X01 (ARM920T core), 20 (and under) to 133 MHz (overclockable to 166 MHz+ in some cases. Some have even reached 256 MHz (not always stable, low battery life). Overclocking ability is random, however all G...

Wow, I never even thought of it affecting Sonic Advance. Very cool.

I think that PS1 will probably come before N64 and maybe before 32X. Highly doubt that 32X will come this year since no developer has said anything about it so far. Another handheld perhaps.

From the readme: "Improved rendering resolution for: Affine background: "Mode7" games, typically racing games like Mario Kart Affine sprites: games that scale or rotate sprites" So basically this sounds like the "HD mode" that mgba and bsnes have. Most games don't use any scaling and should thus look identical. However...

There might be home theater receivers that support outputting audio from two sources at once (and many receivers have HDMI In as well as RCA Ins), but I'm not knowledgeable about them and they're expensive. If you got a set of speakers connected to your TV now, I would suggest just getting analog audio from the TV into your SC-55's RCA Ins, and the...

Yes please. I think this would a brilliant move.

so in this regard the pc is quite special given that any emulator does not emulate the processor itself just can pass it through. Well, this isn't actually true. DOSBox and PCem use interpreters and recompilers for everything, including the CPU emulation. Nothing is executed directly. The fact that the host also happens to be an x86 platform chang...

Having found nothing related in the n00b section, I've reinstalled the OS using the latest files. Needless to say, everything works. :roll: I could be wrong, but it sounds like you hadn't updated Main_MiSTer and Menu_MiSTer. Newer versions of cores tend to rely on fixes and features that get added to the framework, so it's always a good idea to ge...

Chdman (included with every Mame release) can convert back and forth. To convert back to cue/bin, you can use this command:

chdman extractcd -i FILE.chd -o FILE.cue -ob FILE.bin

You may get one bin file instead of multiple, but it should work the same, provided it has all the data and the cue file that chdman generates is correct.

According to the comments in MiSTer.ini, video_mode=6 is 640x480@60. Did you try any higher resolutions?

Why use the SNES core when you can just use one of the many SNES emulators on a PC? An i486 core is of course useful for all the same reasons the other cores are useful. There are multiple benefits to using a MiSTer core, such as consistent performance (no random stuttering or performance spikes), low lag, not having to deal with driver issues, bug...

If I got it right, one of the biggest obstacles to emulating the Saturn on a PC is the tight synchronization between all the different components in the Saturn. Emulating everything in parallel, on one CPU core (mutli-core generally doesn't help due to latency), results in a huge performance penalty. This is always the case with software emulation,...
