problems getting into Advanced GTA SA Video config

[EL_BURRO]

ok, so i got the game, and i got it to work (though i havent found the save games folder, and i havent been able to play cuz it runs too slow, i suposse its because of my old comp) but when playing, its like hey.............. 3 hours later............. yo CJ! come here!.................. 5 hours later........... got on the bike, and so on and so on and so on
i made my graphics card work with best performance, not quality, and it helped me a lot, still, it gets hard to play at 15 or 20 fps, dunno how much i have
okok, i have an old comp ok, but b4 laughing and insulting, please, try to help me, please, pentium iii 866mhz, 384mb ram, 1.5+ gb free disk space, nvidia geforce 2 mx 32mb, windows xp professional with service pack 1
when i try to enter the advanced commands of the video config, i get the THE THE =)!("$=!"$ windows error that says the application needs to be closed because it made an error. DANG IT i said, tried a few more times, with diff resolutions and nothing, and i really want to decrease the resolution, delete shadows and take off that cool-but-slowing-and-huge-motion-bloor-effect
please, i got a new hoodlum crack and some fixes around there (in gamecopyworld, and im sorry if i cannot name the site or something like that, i didnt know) but still nothing

any ideas???
thx for your time bros
