Thanks to Fliplift on the Lemon64 forums, a very rare promo edition of Rock Star Ate My Hamster on the Commodore 64 has been recovered. This was released through The Sun newspaper, and has been missing for quite some time, though a ZX Spectrum version has been recovered a while back.
According to Luca/Fire on the forum thread, Codemasters and The Sun ran a competition with ten runners up prizes being special editions of the game. The special edition includes 7 additional stars, with Kylie Minogue renamed as Koily Mynose instead of Bimbo Baggins.
A download can be found below, though we recommend keeping an eye on the Lemon 64 thread, as a fixed version of the TAP images should be made available shortly.
With thanks to fliplift for the amazing recovery work and finding!
