Here comes my next C64 to Atari 8bit port: Bobby Bearing. This is a WIP version with some issues (for example incorrect graphics in first screen of the game) as well as missing optimizations, but at this moment game is fully playable. Developed and tested under Altirra only, but expected to work on real hardware too.

Wow ! Such a nice Sunday gift :)

Works really well, maybe too fast...

Actually one of those "missing games" for sure.

Very nice. Thanks.

It is faster than C64 due to faster CPU etc. but I don't have a feeling that gameplay is faster. The trouble is, that this game doesn't sync with VBL but instead it runs as fast as it can, so there will be differences.


By "missing optimizations" I was referring to screen drawing routine which happens when player enters new room - it is very slow and annoying. I will take look if it can be done better.

Small problem, hitting the space bar in Altirra seems to lock the game up..

Very nice indeed  :thumbsup:  :thumbsup: nice that you don't fall off the edges too :thumbsup:

As above - space bar locked & too fast on several screens. I got stuck here but maybe this was a trap...


Figured escape to end your go but takes a while to restart and the key repeat is not cancelled.


The PAL artifacting is nice (130XE/CRT)

Look forward to the next version ;-)

Played and reviewed :)


It is a shame about the slow downs which I did notice (same as C64) and also the lack of music which is in the C64 version. Nice port so far though :)

Nice... btw. in Gridrunner VIC-20 port I adjusted the speed to match the VIC original by simple LDX/DEX loop.... so maybe you find few bytes to insert a JSR DELAY... routine and manually adjust to PAL and NTSC.
