DooM for the VIC 20

I just found out about this one, it’s DooM! … on an 8bit.  No really!

I was watching this video of the 8bit guy, and (jump to 19:20) he quickly mentions DooM on the VIC 20.

Over on Denial, The Commodore Vic 20 Forum  Kweepa did the seemingly impossible by using cc65 and some assembly for a somewhat cut down (haha!) DooM on the 8bit.  The source is even available on github.

It has cut down the video rendering obviously, but still has some of the C enemy AI logic, it’s a bit more like Wolf in that there is no height in the cut down levels, but wow it’s still amazing to see.  The sound effects were re-cut from the PC speaker stuff, and yes, even reduced versions of the MIDI music make the cut!

Naturally this won’t run on a stock 20, rather you need to get the maximum 37kb of RAM, and it requires a floppy disk drive.

It’s really cool to check out, and yes it runs on VICE.

I’m more so surprised that this didn’t ignite more 6502, or other non 32bit machine versions of DooM.  You can find download information for the d64 image here, and a direct link here.

NES emulator written in JAVASCRIPT.

Well I guess we have officially crossed the bridge, where multiple Ghz machines can run scripts that can emulate a 1.8Mhz 6502 in realtime.

behold JNES.

And frankly the bigger thing to behold is just how FAST Google chrome is at java script. On my Intel Centrino laptop the google benchmark ( scores 105 in Internet Explorer 8, while Google Chrome scores 3330.

That’s not a typo, Google Chrome is more then 31x faster than IE at executing Java Script.

I’ve got to find out where that whole NaCL thing went to, and where it is.

But seriously, go check it out! Mario in a browser without flash!
