you can build it from source but good luck with that, the build process for DBX is a nightmare. I could not get it building on my linux box without it segfaulting all over the place even when I got it to build (they have their own forked sdl and all kinds of crap)

Zak is one of my fav games. so... I think the weakest LucasArts title would be maybe Loom for me.. I know it gets high praise I just never liked it. I think Sierra's weakest is probably KQ1+KQ2 are the weakest as far as game design goes with no real linking plotline between all the events. ( but …

back in the 90's I created the os-dev faq + wiki and had forums hosted on my mega-tokyo and all (later, a long time ago merged into osdev.org), and we dealt with this guy a lot and it wasnt fun.

If all you read is the wikipedia page sure. It actually accelerates windows 3.1 functions, has a dual screen access which acts as an overlay over the existing screen (so full dual CRT controllers), compound bitblits, all 256 Microsoft Raster Operations opcodes in hardware.

this is whats killing you. they should all just be uint8_t *something; and just strdup them when you read them in, or better use a hash/arry for things that would get repeated (publisher, developer, series, genre). In what way is it killing me? because those fixed arrays are 416+ bytes each when …

so openwatcom has several things going on here. one you should use inttypes.h for printing so like printf("%"PRIu32"\n", var); (PRIu32, PRIu16, etc). check out inttypes. two, never use int/long/short. use stdint.h and use portable types in16_t, uint16_t, int32_t, uint32_t etc. if your using real …

you can get microcontrollers that have usb otg functionality in their stacks. there are so many class compliant things youd need to either be 'this is for gamepads only' or 'this is for usb storage only' or something, and the driver side on dos could be simple or a nightmare but usb is VERY cpu …
