Funny idea to do this in C. I like it. I like blocky stuff in general :-)

Se gitai o ilios was also done to a considerable part in c language.
But all routines which needed speed were of course done in asm.
This proves only, that there is minimum one way, c is not good for demos.
Seeing one white sheep doens't prove, that all sheeps are white, he!
It only proves, that one sheep is white on minimum one side!
Would you mind to release the sources, as i am interested how you did mix c and assembler?

Did you forget fill = yes on the memory area?

I tried using ca65 but I had problems linking data (despite defining segments music wasn't loaded at $1000... it was misalinged several bytes, I couldn't find solution in the docs) so I moved start of the C program upper, and in the lower mem made the handler and linked data (font, music) + the asm program setting up irq and then jumping into C code. I was in big rush as this stuff was meant to be released at Silesia Party 2 and when I finally found out such an mixture is working then I didn't wanted get back into ca65 ;-)

IRQ handler in DAsm? Why on earth didn't you use ca65 that comes with cc65?

@JackAsser : well I thought generally about apllications, I suppoose you won't code c64-concerned utilities on PC in pure asm, will you? ;-)

High level programming not good for demos on a 64K 1MHz machine? Well, now I never!

@Raf: Your logic is faulty. This only proves that C is not good for demos. (And yeah, I did the same journey with Number Seven :)

nah this was an experiment... at least it's realtime ;-) :P and it proves high level programming is good for applications, not for demos ;-)

I kept wondering how can it be so slow, then I saw "this was done in c". aha :D

Yeah, looks really cool at 1000% speed. Too bad a real C64 has no Warp Mode.

CSDb (Commodore 64 Scene Database) is a website which goal is to gather as much information and material about the scene around the commodore 64 computer - the worlds most popular home computer throughout time. Here you can find almost anything which was ever made for the commodore 64, and more is being added every day. As this website is scene related, you can mostly find demos, music and graphics made by the people who made the scene (the sceners), but you can also find a lot of the old classic games here.
