Re: Sega Saturn Core in Development

There's another thread where folks were pointing at the Antonio Villena RAM modules as not working entirely correctly. He went off in a different direction and used 4 chips instead of 2, and apparently some cores don't get along with this arrangement. With the Saturn core being so memory-intensive, it wouldn't shock me at all if it was another unha...

Re: OpenLara on MiSTer

The fact that the PS1 core even works at all amazes me, never mind that it's as good as it is. Creating even a simple 3D chip from scratch is amazing work.

Running TR1 on the PS1 core probably won't look as good as OpenLara, but it will work, and will be very low latency.

Re: Super Weird Issue on Knight 'n' Grail (C64)

I'm not a big 64 guy or anything, but in my own uses, I've always had pretty bad luck with fastloaders. Things just... break. And they often do so in extra annoying ways, like failing after you've invested a bunch of time into a game. Of course, I was always using software versions, often ones that loaded custom firmware onto the drive, not the Act...

Re: MDA Upgrade to Hercules

That would be a cool feature, but probably not that useful unless the Hercules emulation becomes more complete, which looks like a serious pain in the butt. Just documenting how it even works looks like a pain, never mind implementing it.

Yeah, if you're getting disk errors like that, reverting to the standard ROM is an excellent idea. Fastloaders in general tended to fail with the copy protection on many games.

Anyway, that'd only be of any relevance for MIDI sounds that need to be in sync with the video - say a MIDI-based dancing game or MIDI-based sound effects synced with video. For any normal use of a MIDI synthesizer the additional latency that a RPi can add is insignificant. I haven't tested it, but there's no reason why the Pi has to take any long...

Re: Any Way to Limit 68020 Speed?

The last time I was really using Minimig, the 68020 was pretty slow. It felt fairly accurate, much slower than WinUAE with an emulated 68040. I was playing XCom, and the globe rotation was quite sluggish, where it was pretty snappy under WinUAE.

That reference to 110MHz doesn't match my experience at all. Has something changed?

Re: MDA Upgrade to Hercules

Probably almost nothing. DOSBox completely ignores F11 and F12 keypresses and does not pass them to applications. DOSBox is explicitly for games only. I can't speak for spark2k06, but I was assuming that the XT core is supposed to be usable for more than that. I'm pretty sure WordPerfect, for instance, uses F11. On the max speed version of the cor...

Re: Any Way to Limit 68020 Speed?

I think Toni Wilen is a she. It's likely possible to make a cycle-accurate 68020, it's just really hard, and nobody's done it yet in FPGA. AFAIK the cycle accuracy is perfect in WinUAE, and it's got a low-latency "beamracing" output to minimize lag, so that's probably the best spot for full accuracy of later models. It would be nice if th...

Re: MDA Upgrade to Hercules

Didn't XTs have F11? If they did, or could use a keyboard with that key, mapping the mode switch there could interfere with real software. Win-F11 might be better, like Win-F12 is used in AO486 as the menu key. There were definitely no Windows keys until much later.

If XT function keys only went to F10, then obviously it wouldn't matter.

You might be able to dodge the problem by adding an I/O board, if you don't already have one, and hauling the sound digitally via a Toslink cable. From jotego's comment, It sounds like what you're getting is a physical analog pop from circuits disconnecting internally. Using digital sound to a DAC or a receiver should avoid the problem completely. ...
