Re: Metropolis, a proper ZX80/81 demo

Thank you for the newer versions, these work on sz81 as well! However, the version that works well on the real thing but not on an emulator also helps in understanding how things really work. It would be even more interesting if that one works on one ZX81 but not on another... ;)

Re: Metropolis, a proper ZX80/81 demo

It really is a proper demo, because it doesn't work properly on the latest sz81 emulator either (in zx81 mode, it does in zx80 mode)...! As far as I understand it, the in/out combination, which is normally used to produce Vsyncs, is used here to produce Hsyncs. A Vsync resets the "rowcounter", which...

Re: SZ81 compiled for intel Mac OS-X

Just a few thoughts: With UDG, I guess 64 characters are supported rather than 128 different ones, unless one line in the source is changed. In LOAD, the address should indeed be specified in decimal, but that could easily be changed. Printing should cause a bitmap file to be created, in subfolder "...

Re: SZ81 compiled for intel Mac OS-X
