I don't think you can force Proteus/1 to be GM compatible simply by altering its patch map. It has an ability to renumber its patches, but this doesn't apply to drum sets. And while Proteus/1 has several drum sets, none of them are GM compatible.
Windows 3.1 drivers solve this problem by substituting drum keynotes on the fly using a remap table (or so I think). Thus, you can't make Proteus/1 GM compatible without making a dedicated driver that would perform these drum shenanigans. If Sierra somehow did it nevertheless, I applause them but I have no idea how it could be possible.
Anyway, you can take Proteus/ 1XR GM patch set from here: http://files.mpoli.fi/unpacked/hardware/sound … urt/msnd95.zip/. You need genmidi.mpp which is (I believe) a raw Proteus SYSEX patchset with some header. I think it won't help you with drums, but still you may find some use for it.
It appears that the Turtle Beach MultiSound Classic sound card really has a full Proteus 1XR on board. Apart from the header, the Proteus factory sysex for the card is identical to the one for the 1XR module.
I removed the header from the GM sysex and loaded it into my Proteus FX, which is essentially a Proteus 1+Orchestral, which is essentially a Proteus 1XR with additional samples from the Proteus 2.
The sysex works and gives GM compatibility. It uses the "Rock Drums" preset for drums. The downside is that it only uses the Proteus1 samples, which don't recreate certain instruments well.
To summarize, here are the GM options for Proteus owners that I know of:
Proteus 1 "Pop/Rock": only has 64 user presets, not enough for a GM remap. Apparently the Win3.1 driver can be used for remapping on the fly.
Proteus 1/XR: you can use the GM sysex from Turtle Beach Multisound Classic, I attached it here without the header
Proteus 2 or 3: not compatible, they are specialized and lack many instruments
Proteus 1 plus Orchestral: E-MU sold a preset disk called "3107 – General MIDI" but it's not on the internet. You might also be able to use the 1/XR preset file with its limitations.
Proteus FX: E-MU sold a preset disk called " 3123 – General MIDI". Someone on Gearspace claims to have it but doesn't react to messages. 1/XR presets also work but don't sound great.
UltraProteus: E-MU sold a ROM card with sysex for GM compatibility. Someone on Gearspace dumped the cards, they can be found here. Not exactly GM compatible, "Applause" and "Gunshot" instead store drum maps.
Proteus 1000/2000 and other newer E-MU modules that accept SIMM ROMS: can apparently be made GM compatible by adding the "Sounds of the ZR" ROM card, which contains the sounds of the Ensoniq ZR-76, which should sound very similar to other Ensoniq synths like the MR-Rack but not like a Proteus.
