BlackBox8, 64KB CRT works but valid 32KB CRT doesn't

Two types of BB8 CRT cartridges are implemented in Vice. This is probably due to the messy early versions of the Vice emulation, etc etc...

bb8.crt 64KB - it is 32KB modified to 64KB, the freeze button works in it and it shouldn't, even in Vice

bb8.crt 32KB - proper crt, from dump 32KB bin file

Both run in Vice, but only the modified 64KB in Ultimate.

Don't shoot me :] Request to add the ability to run the correct version of BB8.crt 32KB, and disabling the Freeze button on the 64KB version.

This is not a critical issue.

I seriously wonder why those Blackbox cartridges even exist in the Ultimate firmwares... its not like they are useful for anything, they just take valuable logic space :)

They are like viruses :)

But seriously. Commodore fans in Poland grew up on BB3-8 And those who had a 1541 had an AR4 or FC3 clone And now no super-duper cartridges will make them happy as launching this particular crap. :D

Testing various dumps from eproms I collected some CRT cartridges produced in Poland. All of them can be run in the latest Vice. Works a lot with Ultimate as well !! :)

Sometimes as BB3 sometimes as BB8 or BisPlus sometimes you need to change the file size x2 and then convert from .bin to .crt. Emulation allows them to work (seems correct), although theoretically their HW electronics could be different. Each CRT has been tested for basic functions like turbo or tape head alignment software...

I also shared this collection among the community of Polish fans on FB and the forums. In a subfolder there are CRTs that don't work in Ultimate (they work in Vice). I think it's very likely that they will work if you add the correct BB8 32K emulation and they will work as well. https://mega.nz/folder/DAZznDqa#0ZSKNmoMhG23ETpR8ixw8g
