Looks like this is a first on the forum. I found this laying around, which is cool enough in itself. It's dated 1995 and as far as I understand it's mainly a bunch of presentations trying to explain how awesome Windows 95 is, but it also claims to include a pre-release version of the OS. How …

If you could call someone on here a "Roland expert" it's Cloudschatze, too bad he doesn't post in these threads 😀 What precisely do you want me to check on SC-88?

Huh, that MIDI is very different from the one I had downloaded from mirsoft. Maybe same thing as with the Duke MIDIs, i.e. different soundtracks in one file.

I don't think there was PC#122 in D_DM2INT. In D_OPENIN it's the same principle as in his Duke tracks. Fl. Keyclick very most likely.

Running from DOS w/ ctrl menu selection: 3DBENCH2: 16.6 with no cache and a freeze. After that I set back all the RAM tweaks and got 14.0. Results are reproducible, so the tweaks did have an effect after all. 36.7 with L2 on. PCPBENCH: 1.9 with no cache, 5.2 with L2 on. Dead on DX2-66 if I believe …

Just did some RAM tweaking. DRAM Timing 70ns -> 60ns, Fast RAS to CAS Delay 3 -> 2, Fast MA to RAS# Delay 2 Clks -> 1 Clk, SDRAM CAS latency/RAS-to-CAS 3/3 -> 2/2, SDRAM Speculative Read Off -> On. Final Reality showed no difference, results were within margin of error. Half-Life felt subjectively …

Hmm, just hooked up a Roland synth, but was instantly reminded of that BS with DOS games in Windows... port 330 uses the internal GM emulation instead of the gameport MIDI out. SET MIDI=SYNTH:2 MAP:G MODE:0 didn't help me either. Anyone remember what the catch was? There was something with the …

keropi, that screen is 5:4 and unless it has a function to display 4:3 letterboxed you will get a jolted image.

Yeah Socket 7 is awesome. Some DOS games just feel more at home on this than on 2000 hardware. The beige case is great for when I want to have the sense of playing on something vintage, even though it's not the prettiest by any means. The LCD I don't think is actually bad. It's an Eizo L365 from …

I couldn't change frame buffer to double, it's grayed out. U need to register 3dmark 99 in order to be able to do that. Ah... at least good to know that nothing is wrong with the card.

Thanks for the tips. I agree about Windows 95 being a better choice with 32 megs of RAM. I couldn't change frame buffer to double, it's grayed out.

Stick to this if you want to know what you'd get on a real SC-55. Both of your recordings have some differences that I can't explain (more reverb, external maybe?)... they both seem to have the same cymbal behaviour though.

Performance is okay, but I can't understand why Gigabyte does not back bus clock speeds beyond 66 MHz. Just how lame is that :/ but OK, I think with a 200MMX I have a solid basis for a lot of games. The ones I've listed that run bad I've obviously just tried for kicks and there is no reason why I …

Very interesting! Do you know any games that would use ADSR stuff? Frankly I don't think they would go that deep into the hardware when not even using any GS. I would rule it out because it's not shown when I play back the standalone midi file, yet the recordings still show that difference. Note how …

Well, it does have an ATX power connector, but it's still AT form factor... since I can't simply install it in an ATX case I don't see much purpose in being able to use an ATX PSU. I noticed how it says P100 on a sticker on the bottom of the case. The middle button and LED were actually labeled …

Sounds like this goes in a similar direction as Gona's DOS compatibility matrix, only without testing specific games. I'm wondering though, how would you know which games need which mode (inspecting readmes, etc.)? Also I definitely agree that it'd be worthwile to test each chip in DOS and 9x.

Well, a Voodoo3 isn't exactly 1995-1997... but the specs sound fine, I would suggest to use 98SE for convenience. Of course some DOS games won't run properly on a machine this fast, maybe this list can give you a few hints as to what games you won't be able to play.
