Will buy if I can play it on either my U64 / Ultimate 1541 / TC64 / or Easyflash !
In fact I will buy it anyway, provided these formats come as soon as possible !
As stated in the page above:
"The downloadable C64 digital version is designed for use with a C64 emulator – it cannot be used with an EasyFlash cartridge, 1541 Ultimate, or Turbo Chameleon."
Due to the fact that the game was made specifically to take advantage of the cartridge hardware, it won't be released in any other formats.
