UPDATE 07/08/12 : The ROM version was not playable on TurboR (too fast game). It’s now fixed.

In 1984, PSS has published Maxima, an original shooter on tape format. Unfortunaly, the DSK conversion made in 2000 was corrupted (incomplete files) and includes an useless Philips poke. We are more lucky with the CAS version, but there was another problem : the joystick remained immobile on Arabic and Korean machines. On this point, GDX help has been precious as he has found the magical poke : POKE &HFDA4,&HC9 , which is now integrated in the DSK version. For the CAS version, you need to type this poke before the command BLOAD”CAS:”,R as integration leads to a BASIC error message.

This game was without any intro screen, but I’ve created such screen by converting the picture on the game box. The online tool “MSX Screen Conversor” of Rafael Jannone has been very useful ! Finally, I’ve used the excellent DSK2ROM tool of Vincent van Dam to get a nice ROM version !
