I will try to get rid of some patches which might cause problems that you indicated. Where did you find INT 10 error message in lemmings 1? I did not encounter it in the game.

Immediately when running lemmings.bat or when running vgalemmi.exe after choosing PC type. I also noticed that with 5500 cycles (dyn. core) or lower the error doesn't show up when running vgalemmi.exe, anything higher and it won't work. With normal core it's 6500 cycles. Strange...

Edit: The error also shows up when starting Overkill shareware from Epic Megagames, any cycles/core.

wd changed that to see if anyone actually uses illegal pages.
it does judging from your report.

Thanks

Oh and for bug reports please use clean CVS builds, or they will be
completely ignored, at least by me.

No problem, just tried clean cvs build, page 128 problem is there, sound is working fine. I mostly use ykhwong's cvs build, but I will test things before reporting in clean cvs build from now on. 😊

If they can't initialize adlib, they seek for tandy (thus using that 0x80 "page"
number). Should not happen if you use the default core/cycle settings.

Clean install of DOSBox 0.72, with latest clean cvs binary (all default settings), page 128 error is still there while launching Overkill and Lemmings.

Edit: You can get Overkill shareware here http://www.classicdosgames.com/shooter.html

It was programmed to quit DOSBox if the page number is more than 7. As qbix mentioned, wd made the changes 4 weeks ago. It is easy to get Overkill to work by simply disabling the following two lines in int10_char.cpp, but DOSBox developers might have other solutions against the use of illegal pages.

1if (page>7) E_Exit("INT10_SetActivePage page %d",page);
2...
3if (page>7) E_Exit("INT10_SetCursorPos page %d");

Does using 0x80 work for Tandy/PCjr mode? I think it should if not. Also, what does the VGA BIOS do when encountering an invalid page? Return some error? In which case DOSbox should do the same?

Same as dosbox, we just e_exit to check the corresponding games.

Will release version of DOSBox just show page error and not exit, or will it stay this way? 🙁

They surely won't exit on this, and not even display some logging.
