Any chance any of you guys could tell if it works with this GUS clone you have? (or with a real GUS) It requires ULTRAMID.EXE to be loaded. I took a few minutes to test it on an InterWave-based Gravis card in two different configurations. The first was with Mega-Em 3.11 providing UltraMID …

If you don't think there is a short between pins on the chip, and it still doesn't find the ROM with no SIMMs installed, you have other problems to worry about. I don't think that trying yet another pair of SIMMs will cause any major new problems, but it isn't likely to solve anything, either. The …

I have finished and tested my card Do you use leaded solder, or is there a lead-free formulation that gives such clean-looking joints now? The older stuff I have seems to end up slightly blobby, regardless of temperature or other factors, and always leaves a crust from the flux core behind. It also …

From the pictures, it looks like someone attempted to repair or modify the card at some point. So, there are a few things I would suggest that you try: Under bright light, check the large InterWave chip, looking to make sure each pin sits on the corresponding rectangular spot on the board. Also, …

normally that wouldn't be an issue since you are supposed to install a ROM and configure the jumpers but I want to wait for the IW78C21M1 one For anyone who has yet to build the card, it is important to remember to set JP4 and JP5 as instructed on the card, whether your ROM is in place or not. …

So, I'm guessing that the easiest way will be to get 2x4MB RAM that I wanted to do anyway? My PnP is rev 1.0, BTW. I can't find a photo of this card with all the pins visible, though. I also have a V1.0 board. Mine originally didn't have any pin headers installed for JP8. It was permanently …

Mega-Em 3.06 loads samples from RAM instead of ROM on a PnP if I'm not mistaken. Don't know if that is helpful with understanding Mega-Em's behaviour. I don't know if that's the case for the UltraMID functionality, but GM and FM emulation are definitely ROM-based on the latest versions (3.11, at …

There is a wealth of information inside, thanks for the link! I will see if I can easily add support to DOSMid. Don't have any GUS hardware to test, but I noticed DOSBox got some GUS emulation, so that should be enough I guess. Will post here when/if I get this done, so perhaps one of the GUS-clone …

RAM isn't essential on one of these cards. In case there is a problem with your SIMMs, you may want to try removing them until you get the card working. Can you post the output of the SET command under DOS, as well as iwinit -v9? It would also be useful if you attached your IW.INI, found in GRAVIS\ …

With initial testing complete, I can say that Mega-Em worked well enough with the custom 2 MiB ROM to validate the theory. The sound produced via General MIDI emulation is quite acceptable, even with a custom ROM, as long as the instrument set used is fully contained within the first ROM bank. That …

For now, the least expensive and most convenient approach is to program and test the 2 MiB ROM image that I have already generated. I think I'll have time for that later tonight. Based on those results, we'll be able to decide how to proceed. I've never seen that prototype before, but it looks like …

I have a little more information to share regarding Mega-Em. The good news is that it should be possible to get it running on most configurations, even with the common Microsoft HIMEM.SYS version 3.x, though it's not necessarily ideal. Although still somewhat finicky, Mega-Em is not nearly as picky …

If you have a system with 64 MB memory or more then EMM386 in combination with HIMEM 3.x have a bug that prevents MEGAEM from loading. MEGAEM reports something like "Can not expand server pages". It is not a MEGAEM issue and can be fixed by either using an alternative memory manager like QEMM386 or …

So far, my efforts to test Mega-Em have been nothing short of exercises in frustration. I have tried just about every reasonable combination of options for EMM386, and even several versions of DOS and EMM386. Eventually, it still results in the message complaining of the inability to enlarge the …

Or you get the Original ROM from UTSource: https://de.utsource.net/itm/p/457141.html I bought it just to see if it was programmed. And it came with the right ROM content. (I own a Gravis Ultrasound PNP and compared the dumped content). It's interesting that apparently nobody thought to try that …

hi, just to be sure: as the M29F800 SOP44 chip has to be programmed, do we program " Gravnocd.rom - ROM file that will be written to the EEPROM" on it, is it that file ?

I will agree that C isn't perfectly balanced, but in the particular case of the first set of recordings, it seems to be the best match for the Roland balance, if I'm not mistaken. A and B seem to differ significantly from Roland at the beginning; the balance between the saxophone and other brass …
