Space Harrier Update 2018

Tue Oct 16, 2018 2:02 AM

Updated version with RastaConverter based title screen, serious bug fixes and some other bits and pieces to make things easier.

Not tested on real hardware yet, so interested if you come across any problems.

*CONFIRMED CRASHES WITH CONSOLE KEYS PAUSE*
NTSC colors may be poor still
 
*Fixed on attached versions*

 

NB .bin version is for AtariMax 8Mbit cart type (old and new)

 

New title screen and attract mode


Short display lists on real hardware?

Sun Sep 16, 2018 2:54 PM

Do really short display lists with just a few dozen scanlines before the jump and wait for vblank work without rolling on real TVs and monitors? The display list doesn't need to be padded to some minimum length?

They work on emulators, and "wait for vblank" gives the impression that it should, but my real Atari is packed away, so thought I'd ask first to be sure. Thanks!

Mads assembler best way to end align code?

Fri May 4, 2018 2:19 AM

Not just Mads, but I'm kinda new to Mads and maybe there's an easy way in Mads:

I've some compressed data/code where it allocates memory to the uncompressed size, but to save memory the compressed data should be aligned to the end of uncompressed area, not the start. Obviously I don't want data the full size of the uncompressed data to be assembled.

EG

/0000000000000000/ (uncompressed)
/0000000000xxxxxx/

X being the compressed data.

Anyone have experience of doing this without it being run through an external packer utility?
Thanks!
