Re: Cant change to C

Posted on 2006-04-06, 15:41

One thing, Im on xorg, and the : wasnt working, and after a quick search, it looks like dosbox has problems with xorg, so I ended up getting the colon in by holding down ALT and typing on the number pad 058. Would that have anything to do with it? Try setting "usescancodes=true" in your config file …

I'm still experimenting with MPEG (I still get file sizes larger than the original format) That's not very miraculous. IIRC, MPEG2 enforces a rather high percentage of keyframes (one in 18 for NTSC, one in 15 for PAL I believe). Also MPEG2 is tuned for natural images (soft edges, gradually changing …

Edit: Yep, it's certainly due to OpenGL. I can pretty much make it hardware reset at will by switching from windowed to full screen a few times. No such problem with ddraw. There is a warning in the readme about OpenGL, but this never happened before. Maybe it's a combination of the new drivers or …

Qbix wrote: The -O4 option.. I did hear about that. but didn't find documentation on what it does. Actually it's just a future-proof variant of "-O3", the highest optimization level that gcc currently supports. Anything higher than 3 gets treated like -O3.

Finally, for anyone compiling sources by themselves: gcc-4.1 is pretty amazing, as far as I have seen so far. If you can, use it for compiling dosbox. I'm using 4.0.2. For that, I found that using profile guided optimization adds a lot of speed. "configure" with CFLAGS="-O4 -fomit-frame-pointer - …

I got a crash within about 2 minutes of using the new DOSBox. Well, not a crash so much as a hardware reset. What OS are you running? If it's not Win 9x, then a hardware reset is usually (though not always) a sign of some deeper trouble, not of a buggy application. For example, are you sure your …

"Now?" :disapproving: Ultima VII has been playable for a very long time. I would know, because if it wasn't I'd be at the front of the line begging for it to be fixed. It works perfectly, I run it at 15000 cycles for best results. Really? I find it way too fast at that speed (it's almost impossible …

Re: Monochrome EGA and VGA

Also, software that uses the monochrome EGA mode 0Fh doesn't work, but software using the monochrome VGA mode 11h does work. A fix or a regression? I can't tell you anything about the rest of your question, but this one doesn't seem to be true. I just tried out all the modes with QuickBasic and …

Strategy game, requires loading of fix8x14 utility so text is not scrambled. Does it require this on every system, or only on those which don't have an 8x14 font built into their VGA BIOS? 'cause many newer cards don't have such a font since it's only for the EGA modes that are rarely used nowadays …

New small patch: Handle backspace in int21/0a

Posted on 2006-02-28, 18:57

I've put a new small patch on the SF patches page. With it, backspace is handled correctly in INT 21 / AH=0x0a "Buffered Input". This function is an old DOS function for reading a whole line of input from the user. It's rarely used by newer games, but for example the Infocom V3 games (MS-DOS-based …
