Z64K Beta (2017/08/05) is released. Pixel exact emulation of the Commodore 64, VIC 20 and Atari 2600 written entirely in Java. The emulators should run on any platform with an updated java runtime environment installed.

Z64K Beta Changelog:
version b - Fixed a bug with FSDIR. It was the reason why the upgraded version of CP/M 3.0 PLUS would not load. It's a bug that has made me scratch my head for ages, but now that I found it, it was so obvious what the problem was. :p
Updated some fast serial logic. Upgraded version of CP/M 3.0 PLUS works.
EXTRA INFO.This version of c128 Beta has a portal page to all emulators. It's not complete but to preview you can either update the Main-Class: in the Manifest.mf file to portal.Z64K or run the class using the command line. eg. java -cp C128_Beta_2017_08_05.jar portal.Z64K
