ZXSP v0.8.0 Pre21

ZXSP v0.8.0 Pre21 is released. zxsp is a simulator for the historic Sinclair ZX home computer families for Mac OS X. zxsp simulates the black&white models ZX80 and ZX81, the Jupiter Ace, the ZX Spectrum models with 16K and 48K ram, the Spanish clone from Inves, the +128, +2, and the +2A/+2B including the Spanish and French localised versions.

Video Beam Indicator Yeah! Finally, the video beam indicator is back again. Right now only for the color machines, but the b&w machines know exactly where the beam currently is anyway. ;-) The video beam indicator is a red&yellow blinking cursor at the current position of the video beam. It is activated when the cpu clock is throttled down to 100 kHz or less or when you single step in the debugger. This is an aid for anybody who wants to write a demo with some critical timing. For those who only want to play games it's a "nice to have" for curiosity. B-) Load assembler source Now it's possible (again) to load snapshots and tapes from assembler source. The source will be compiled by the built-in zasm assembler and the resulting snapshot will be loaded as if it was initially selected to load. The source file is stored in the "recent files" list so that reloading it is easy. It's not trivial to get the headers of .sna or .z80 files right, so i have included template files in this distribution. Supported target file types for assembler sources are .sna, .z80, .ace, .rom and .tap.....
