C64 fanboism ? XD yes meh thinks
If you think so. Yes, the ripped arcade graphics used in this CPC 2012 fan game looks really nice. Gameplay-wise it surely doesn't beat the C64 version and cleary not the Amiga port.
btw: Manfred Trenz wrote the C64 version in a few weeks, because he got not much time to do the conversion.
Edit: And yes, the PC Engine and Sharp X68000 versions are the best ports, besides the 1:1 PSX port in the "R-Types" compilation, which is NOT an emulation.
