This small release fixes an important bug in the GEMDOS drive and enables MIDI as a logging device. GEMDOS drive fix This fix solves a memory management issue with the initial release. It replaces a system call with another one, that was made available in TOS starting from version 1.04. So this fixed version now only works on TOS versions 1.04 and up. Everything is explained in the updated documentation.

Happy new year! It has been quite some time without any zeST release, so let’s celebrate this new year with a new release! On the menu: a brand new GEMDOS drive, real-time clock implementation, improvements around network connectivity and joystick/gamepad management and some driver updates. A new GEMDOS drive The GEMDOS drive is a new way of implementing a hard disk drive on zeST. It maps the contents of a directory on the local Linux system to a logical disk drive on the Atari.

Here comes a new release with performance improvements and useful improvements on the software side. Turbo mode optimisation There has been a pass of optimisations in the memory accesses in Turbo mode. The two wait cycles on reads are gone, and read burst management has had its latency reduced by a few cycles. Performance has therefore improved, as you can see on the new results: The average peformance is now 540% of that of a real ST, which is 28% faster than the previous release of zeST (420%).
