Hi Paul,
I have reproduced several of your problems. Mirror Magic seems to work okay, but I have not tested the sound there. Bolitaire, trying to start a new game in Dosemu2: Shutting down Allegro Exiting due to signal SIGSEGV General Protection Fault at eip=0004c197 eax=00173484 ebx=00000212 ecx=00000000 edx=0003014c esi=00000054 edi=0018dc58 ebp=0020d9a8 esp=0020d960 program=C:\DOS\GAMETEST\BOLITARE\BOLITARE.EXE cs: sel=0107 base=02121000 limit=00d5ffff ds: sel=010f base=02121000 limit=00d5ffff es: sel=010f base=02121000 limit=00d5ffff fs: sel=010f base=02121000 limit=00d5ffff gs: sel=011f base=00000000 limit=0010ffff ss: sel=010f base=02121000 limit=00d5ffff App stack: [0020dc58..0018dc58] Exceptn stack: [0018dbb0..0018bc70] Call frame traceback EIPs: 0x0004c197 0x00014a5a 0x0000219f 0x000e04b8 C:\dos\gametest\BOLITARE> Trying to start a new game again fails immediately until you delete the (long name!) statistics.fyl it made again. The mouse cursor uses the wrong scaling of coordinates in DOSEMU2 at the moment, so only the upper left can be reached. There is some built-in sound player, but I do not know how to open a file to play with that. The logo shown in "about bolitaire" looks damaged, as does the "about author" picture of the author, seems to be using the wrong color depth or palette here? Use escape key to close windows without using a mouse. Default CONFIG.TXT uses color=24, trying 15 or 32 is going to make DOSEMU2 fail with "vgabios: unimplemented, biosfn_write_teletype:623" and Bolitaire stays black. Bolitaire also accepts 8, 16 and 24 bit/pixel, needs more depth above 8 for background images. Seems it should be custom_driver, not drive, in config. Author photo: blit(data[YOGESH].dat,form1,0,0,15,35,160,120); DOSDEF: Tiny DOS Defender Asteroids style game, 10 kB, works okay in DOSEMU2. Too few files to need extra dir? FLPYBIRD: Tiny Flappy Bird style game, works in DOSEMU2, simply uses MCGA BIOS mode, should be no problem, but it uses I/O ports 42, 43, 61 (for sound), 3da (for VGA sync), KRAPTOR: Seems to work okay with default settings, has sound, mouse coordinates wrong in DOSEMU2, use tab and enter to navigate menus without mouse. 640x480. Liquid War: Text documents seem to use wrong codepage? Same mouse cursor problem as always, default 640x480 menu and 320x240 game, up to 1024x768, all working in DOSEMU2 (menu resolution changes switch immediately). Not sure how the game plays, keyboard moves a circle? Magnetic Scrolls: Indeed only an interpreter, you need to have levels to use this, e.g. from a game you own. NGE Nibbles: Probably just MCGA graphics, runs WAY too fast to play in DOSEMU2. First slowly fades in the level, then you instantly run against the next wall :-p Vertigo: Flight simulator in MS FS4 generation graphics, seems to work, but too lazy to learn all special keys to actually fly that plane, sorry. WING, Wing Is Not Galaga: Galaga arcade style game, runs in 640x480 graphics mode with sound, but crashes as soon as you select "continue on": Exiting due to signal SIGABRT Raised at eip=00076c86 eax=0013dd44 ebx=00000120 ecx=00000000 edx=00003ac0 esi=003392d0 edi=002c14b8 ebp=0013ddf0 esp=0013dd40 program=C:\DOS\GAMETEST\WING\WING.EXE cs: sel=0107 base=02121000 limit=0034ffff ds: sel=010f base=02121000 limit=0034ffff es: sel=010f base=02121000 limit=0034ffff fs: sel=011f base=00000000 limit=0010ffff gs: sel=011f base=00000000 limit=0010ffff ss: sel=010f base=02121000 limit=0034ffff App stack: [0013e548..000be548] Exceptn stack: [000be4a0..000bc560] Call frame traceback EIPs: 0x00076ba4 0x00076c86 0x000312f7 0x00072b9b 0x00003890 0x00003e36 0x00004ae3 0x00007cf4 0x00008285 0x00006b5a 0x0000670c C:\dos\gametest\WING> So apparently VirtualBox 6.1.22 has a surprising amount of problems with DOS games and I wonder why that is the case. I guess all games work equally well or unwell for all boot options, not just for your choice "3"? Many DOS games have wrong mouse coordinates in DOSEMU2 for me at the moment, with DOSEMU2 version 2.0pre8 6157. I think I have heart complaints about MKEYB in VirtualBox before, are you using the most recent VirtualBox version? > bolitare: when quitting game, black screen, no DOS prompt Not here, but fails to start as soon as statistics.fyl exists. > dosdef: Have seen division by zero with config = 4 > config = 3: invalid opcode at 2818:163e 0002 0007 98BD 8F57 etc. Does not happen for me. > flpybird: black screen when launched Works for me, simple MCGA graphics, needs VGA port 3da and speaker/timer control over ports 42, 43 and 61. > kraptor: graphics seems wrong, but can play, hang when quitting Works for me, probably VESA graphics at VGA resolution. > liquiwar: graphics seems wrong, hang when quitting Works for me, but game strategy unclear for me. Probably VESA, 320x240 to 1024x768 resolutions. > magnetic: need a (commercial?) story file This should indeed be moved to game system EMULATORS and to the Bonus category, not default part of the install CD or USB images, not useful enough for that. > mirror magic: graphics wrong, was not able to read what seems to be text Looks pretty normal, no crash either, I can play it by clicking on movable mirrors and similar things. > nge_nibbles: I think something is wrong (very slow, miss most of the > level graphic) The fade-in is relatively slow in DOSEMU2, while the actual game runs way too fast. Apparently MCGA mode. > vertigo: hang when quit game I do not know how to play this flight simulator, but it seems to work okay. > wing: color seems wrong, hang on exit, mouse movement not too responsive Actually crashes when I try to start playing, menu works. > Seems OK: > boom, btitanic, eliza, empong, ev4de, ewsnake (italiano), fmines (slow), > freedoom, > gnuchess (NANSI), hangman, ivan, mistral, nethack, noudar, paku (pacman), > qtetris, snova, sudoku86, vitetris, ww1, zmiy I have not tested those, given that they work for you.
