I tried Rabbit Transit again. In the PAL version there is no starfield but a setting sun instead. I also checked the NTSC version and it has some sort of starfield effect. Unfortunately Distella couldn't disassemble the ROM correctly, so I had to do it by hand with a hex editor. Therefore this information is untested and probably incorrect. I think what Rabbit Transit does is loading HMM0 with $70. 18 cycles after the next STA HMOVE it does STA HMCLR, wich ends at cycle 21 and seems to trick the TIA, too. I have not tested if the resulting starfield is the same as with a second STA HMM0 or a different one, yet. BTW Dan Mowczan at dano@xxxxxx used to sell shrinkwrapped Superchargers some time ago on RGVC. Maybe you should try contacting him.
