Erm... erm... I am seriously lacking words... UNBELIEVABLE!

Also the music in the note is awesome.

@Skate sorry. It was completely unintentional. Your nickname mistakenly associate me with something else. I corrected it.

@wisdom: thanks for the source code.

@Mr Wegi: how come you write both my handle and my product's name wrong? :)

One small correction to one of the comments I wrote in the source:

"cast 40 rays for each screen column" was actually supposed to be "cast 40 rays, 1 for each screen column", of course. Thanks God, I am not shooting 40 rays per each column, really. :-)

Also, thanks JackAsser, I didn't think of it, nice one.

Lovely! And thanx for the nice source. Wanna shave 2 bytes? Then get yourself a new sign-extender. From the top of my head:


lda #$80
cmp steps,x
adc #$7f

for once this is a source that has comments decent enough to be useful - a bunch of people around here can learn a lot from it =D

Uploaded the source code as a separate download. Please note that this file only include the source code, and not the binaries.

Very thanks to Nightlord, Xiny and Wegi for their comments, and once more to everybody else who took their time to give some feedback. You guys really made me happy, I need to say. :-)

Thank you!

What WHAT? Without looking at the code. If you do that then you are great :) It is so great that I simply no words. It is as epic as Skate Rottoprojo64 256b. It really is - unbelievable. Big respect Wisdom - 10/10

This is awesome! Both codewise and playwise. I could imagine play a full game like this with music and the whole package. Amazingly, no matter what :D

this is just insane! no way no how! mind blowing shit!!!! incredible!!! i am out of words...

Wisdom has always been one of the best coders I have known. But even knowing how good he has always been didn't prepare me for this insane achievement.

The best scene prods are the ones that inspire you to make prods yourself. I had silently watched the 256b/4K categories for years with little interest in making one myself (Krill's Artefect was an exception). 1bir is the first 256 that ever made me go "hmm I'd like to try my hands on some 256b magic". Obviously I can't do something like 1bir :)

Crescent roxxors!!!!!

I personally replaced the ugly patched kernal in ccs64 (it's a rev2 with replaced lda $d021 with lda $0286 anyway) with rev3 from vice, for the few times I should use it. I never understood why the ugly hack instead of using a normal rev3.

Groepaz, I did not like this fixing matter myself, as I agree it is the emulator's responsibility. I do not have a REV1 KERNAL, so perhaps it is as you say a general problem with this revision. I am just expecting AR to have $D8 on return from calling screen initialization at KERNAL (down somewhere $E518), which "normally" calls $EA24 at the exit and sets $F3/$F4 ZP pointer, and AR to $D8. This does not happen with the revision in CCS64, so it messes everything up, as the code depends on screen row address table in ZP to have $D800 hi-bytes, instead of the usual $0400.

CCS64 still comes with a weirdo patched kernal, which is a mix from REV1 and REV3 - i wouldnt create programs specifically taking care of it (fix the damn emu instead).
that said, your code simply may have problems with REV1 kernal in general?
User Comment

Added a version for CCS64. This file does not contain the original binaries, just the modified ones for CCS64. Apparently, CCS64 uses a modified KERNAL and some routines do not behave exactly as in the stock KERNAL. As 1bir depends on some values returned by KERNAL, a workaround was needed.

I will also upload the source code soon. It is not something complex, but I thought it would be better to clarify some points with comments.

Once more, I would like to thank you all, whoever gave much appreciated feedback in any form such as comments, likes, votes. The last couple of days of my life was really among the best, thanks to you all. I have done many things in life profesionally (in technical manner) and I got appreciation for some, personal satisfaction for others. But nothing could compare with what I received for this small demo. Strange, but true.

Hearing comments from such coding legends like Glasnost, Cruzer and Axis was really huge for me. Thank you mates.

Also thanks for your sweet celebrations in Turkish and whoever took their time to write a comment here or contacted me elsewhere. :-)

Lastly, I want to send my greetings to Bliss (Ibrahim Gumus). I forgot to write it in the note file, so here you go. :-)

Unbelievable! Is there a sourcecode release for this? I think, we could all learn something from that.

Agree with Cruzer. This is very impressing for only 256 bytes. Great work! Now I'm really looking forward to the 64kb version in a demo ;).

Fantastic! Of course butt-ugly and slow, but that's ok for 256b. It's incredible that it's even possible.
User Comment
Submitted by Oswald on 21 April 2013
I'm sorry, but I can not tolerate uglyness and slowness even if the size is small. There has to be a line. I tried to like this but its much slower than I expected for no textures and 8x8 pixels, the fisheye bug is terrible, and almost impossible to orientate myself in 3d. I like you wisdom from the good old irc times, but I cant like this sorry. however I like the time & hacking invested if I may say this after all this. :)

I've been impressed by some 1k js effects recently and was thinking, no way could the c64 do the same, but here I am proven wrong and amazed to see something like this in less than a 1/4 of that. Great work!

This is great. I recently went back in time and played a game that I was so addicted to.. It was Double Dungeons on the turbo gfx 16 (pc engine).
While playing, I was curious if it would be possible to bring it over to c64, this shows me it's possible.

Great work.
