I'm testing some games I had handy, here's what I found:
Note: I'm only testing games far enough to get into the first level without obvious errors, I'm not playing any farther. So they could still be buggy!
Alien Carnage/Halloween Harry: RunsAvoid The Noid: Runs, but with graphical corruption.
Bio Menace: RunsBlake Stone: Runs, but with minor graphical glitches
Cannon Fodder: RunsChex Quest: RunsCorncob 3D: crashes with divide error on level launch
Cosmo's Cosmic Adventure: RunsCrystal Caves: RunsDoom: RunsDschump: RunsDuke Nukem II: RunsElectroMan: RunsGalactix: RunsGod of Thunder: RunsHocus Pocus: RunsJetpack: Does not load (no error, just hangs after running) (I used the freeware version, not shareware)
Jill of the Jungle: RunsLemmings: Hung at first level (in VGA/PC mode, didn't test others)
Major Stryker: RunsMonster Bash: RunsMonuments of Mars: Runs, but with graphics issuesMystic Towers: RunsNinja: Runs, but with the same graphics issuesPickle Wars: RunsPrince of Persia: RunsRailroad Tycoon: RunsRaptor: Call Of The Shadows: RunsScorched Earth: Crashes with an invalid opcode error.
Secret Agent: RunsSolar Winds: RunsStar Goose: RunsSuper Solvers: Gizmos and Gadgets: RunsUgh: RunsWord Rescue: RunsWolfenstein 3D: Does not load (no error, just hangs after running, with or without FPU)
Xargon: RunsZone 66: I wasn't able to get it to run using the freedos boot disk, but it may be possible with a real DOS bootdisk
Looks like I broke something in r11-WIP (edit: fixed the CGA modes). The corruption looks similar to Moments of Mars and r10.12 (version I tested with, because I didn't have r10.13 .jar handy) didn't have that graphical glitch.
And besides, run should be made using v1.1 barring v1.0. having serious glitches not present in v1.1 since v1.1 has FM music and EGA graphics (v1.0 had CGA).
NO_FPU hack fixes those graphical issues for me (by preventing game from using FPU).
I tried Freeware version and was able to enter first level and move there (IODELAY/HRETRACE/SB16/FPU)
r10.x doesn't seem to have those issues (edit: neither do later r11-WIP versions). Unfortunately, text looks like mojibake (edit: I think it is caused by VGA BIOS not honoring user-defined characters and is still present in newest Qemu VGABIOS, so I can't do much about it).
r10.x should not have the graphics corruption (edit: Also later r11-WIP versions should fix it).
That one runs for me. NO_FPU is needed to prevent graphical glitching. I tested both with shareware version and Blake Revolution, which is hack made using registered version.
I get that game to start (edit: Strange, I can't get it to even load anymore). Unfortunately it does not work as it crashes instantly if you start the actual game.
