Well well.. 3Sec to render... Beware because, on boot, the genesis lag during approximatively 2 seconds. You should startup the vdp and display a hello world and then draw to be sure of the time it takes. Why is the rom 800KB ? You made a full game? Bye

That's why I put it in the abandonned projects section...

It's because it was based on some of my older projects. There's lots and lots of dead code/dead data in it. ;D
you could go buy some cheap 486 laptops and tear the lcd screens out of them, but the problem with those is that they are like 13" or 14" so you would have a big portable.. lol
maybe you could make a better custom portable console then a 120x46 or whatever resolution. do 320x200 and make it play duke3d
Or maybe open up an old Palm III and just wire some proper joypad controllers to it. ;D
or we could all be like sega and make this big complex system (*cough* saturn *cough) that has amazing capabilities, but is insanely expensive and bugy.
on a more serious note, get a lcd screen like the size of a gb advance and use that. but make it be more powerful than a 8 bit cpu. try a 68060 @ 75 MHz with like a 256 color or 16 bit display using something like a SiS chipset. and a YM3812.
if a 68060 is too expensive, theres a store in austin that sells junk 386 and 486 cpus and entire systems for 10 bucks, so you could have all the cpus you ever needed and un-solder the extra crap like srams and isa slots for extra parts
i wish i could do all the advanced stuff in electronics where i could build my own computer out of spare crap lying around here. i have a bunch of 68030's and some 68881 & 2's, some custom videocards for old macs i have around and an lcd screen.
i had to read tons of manuals and how-to's to do the sh2 overclock lol.

there are easy parts, and there are hard parts to building a computer just from bare cpu's, some memory, and logic chips. what is easy for me are the data and address signals, since they're self-explanatory, and connect easily. the hard part is control. for the simpler cpu's, like the z80 or 6502 or 8051, there are not many control signals, and memory decoding is very easy because all these cpu's are slow and don't need wait states unless someone's making like a 100 mhz z80. the harder cpu's, 68060, pentium, x86-64 require a lot more
