It’s been ages since I loved this game … actually since the very first time I played it, I really fell in love with it. Maybe because it was based on the Barbarian (Psygnosis), which is another one I think simply rocks!
Anyway we’ve got another ZX Spectrum port on the MSX, quite playable anyway, but I wasn’t able to find a proper version of this game (.cas or .rom) fully working on MSX1 machines nowadays (not able to boot on pleny of them , HB-10P for example) or without corrupted graphics.
After several sessions disassembling the game I found plenty of great stuff, and I am going to share some in here.
First, find the .cas version without any VRAM fast access issue, ready for our MSX1 machines. On top of that this hacked rom version, adding infinity energy plus ammunition. Sources included (sjasm friendly syntax).
