Release id #103143 : C64anabalt

Works perfect on the real thing here. Indeed, not easyflash compatible, but since no-one claimed it would be, no problem. (which goes for most eprom images btw)

Nice work on the game, can't really tell which version I liked best, both have it's ups and downs. I did find the scrolling in this version somewhat imperfect though. It stutters a bit.

Like quite many of the entries to this compo, this one hast a faulty crt-header.
In particular the CHIP setting and the GAME/EXROM lines.
Everyone should consult:
http://codebase64.org/doku.php?id=base:crt_file_format
And not just copy&paste:
http://codebase64.org/doku.php?id=base:assembling_your_own_cart..
(which is for 8 KB).
However, this should be no issue for the cart-releases on real hardware anyway.
Vice is much to forgiving in that aspect.
This would be a proper set up:
*=$0000
.asc "C64 CARTRIDGE   "
.byte $00,$00
.byte $00,$40
.word $0001	;version
.word $0000	;crt type
.byte $00	;exrom line
.byte $00	;game line
.byte $00,$00,$00,$00,$00,$00 ;unused
.asc "NOT EVEN HUMAN"
name
.dsb ($0040-name),0
;chip packets
.asc "CHIP"
.byte $00,$00,$40,$10	
.byte $00,$00	;chip type
.byte $00,$00	;bank
.byte $80,$00	;adress
.byte $40,$00   ;length

People should just create a .bin file and then use cartconv.

I guess these are broken then too:

They do work on a stock eprom card though (after removing the crt information etc), and for convenience sake I was assuming this was the same for Canabalt.

(and yes, vice rejecting those would be quite helpful indeed.. saves a lot of headache)

Yes - this would save me some hassle too...

ME: Sorry, that CRT doesn't have the correct header.
CODER: Wut? It works in VICE!
ME: *provides codebase link*

No worries, the recent chip header parsing updates
make sure that only valid information is accepted
there and broken files like these are rejected.
