Wow it works great on FunnyMu Emulator.

Yes please add the same fix to Planet Defender.

I would eventually distribute them through the official "Roms page" in the CreatiVEmu website, if you agree.

Hi Mobsie, any news about the Planet Defender fix?

I suppose it could be included in the new Multicart which is being produced soon, in replacement to the "standard buggy" version of PD

I took another look at this - and it get's really interesting to me when you compare Deep Sea and Planet Defender.

The disappearing terrain and missing air bubbles is caused by the colour table being at the wrong place.

So in Deep Sea they are air bubbles - in Planet Defender they are planets :)

See attached.

These are for 6K ROMs as downloaded from the main site.

If you want the terrain all the time - change offset 0xE1A from 0x00 to 0x10. This is the same for Planet Defender.

If you want Air Bubbles, or underwater planets - change 0x144f/0x1450 from 0x00 to 0xA0 and 0x1578/0x1579 from 0x00 to 0xA0.

I've gone with the same colour 0xA0 as the sand - but change to suit - you may prefer magenta underwater planets :lol:

Actually Deep Sea even has stars - which are drawn but as they have no pattern nothing is shown.

The stars are
0x128 00 to 02
0x12A 00 to 40
0x12E 00 to 04
0x131 00 to 08
0x135 00 to 04
0x137 00 to 40

This adds pattern to the stars and provides the full flatulent diver experience :lol:

first time I see this game, and I wonder how the smooth scrolling of the background is possible? I always thought that the TMS9928 was not capable of that.

Is done with different set of the tiles, shifted 4 or more times. See and read my Scrample demo, i use 4 different char setup for 2 pixel scrolling.
