we have several versions of Bad Apple for the A8 now. Think the first conversion on the A8 was done by Playsoft in four different resolutions, all working with either 1MB RAM or cart. (64k RAM is enough for the cart versions). Next came a bigger version by R0ger (approx. 4-8 MB) which was a fileversion that should best be loaded from a harddisk, but can be loaded via slow SIO (with or without ultraspeed/highspeed/turbospeed) as well. Loaded it very slowly (aka slow-motion, but successfully!) from a MyDOS image with SIO2PC... afaik, 64k RAM is still enough for this version.
Last year two more Bad Apple versions for the A8 were presented at the Silly Venture, one version (by JAC!) requires The!Cart (128MB flashcart for the gfx) *AND* a data recorder (for the audio sound via SIO Audio-in) and another version (by TeBe) that requires Rapidus (20Mhz, 16MB RAM) and most likely a harddisk (would take a bit too long to load from a data recorder, but maybe funny using a 20Mhz device with a data recorder). Both of these SV versions look very good at a show / presentation... but for home use I prefer Playsoft's and Roger's A8 versions (my personal opinion). There is also youtube, where one can watch hundreds of Bad Apple conversions on almost any platform... waiting for: Bad Apple on the chip of my credit card / identity card / health card... (but would not be surprised if such a thing already exists).
