Re: [hatari-devel] Hatari 6301 emulation

[Laurent Sallafranque <laurent.sallafranque@xxxxxxx>]

I started to code an emulation of the 6301 cpu a few years ago (the code that is actually into the Hatari repository), but I stopped it before it works completly).

Many instructions were emulated, but if I remember well, not all of them.

And the integration of this code into hatari is not yet done (I mean the clock of this 6301 CPU)

Hi,

As some might've noticed at A-F or in #atariscne there's been some activity over the last few days getting what was rumoured to be a dump of an unreleased Audio Sculpture v1.5 to run. It has involved some detective work by both myself as well as Nicolas, and has turned up some unsupported quirks in emulators.

I'm currently looking at the code that decrypts the actual AS executable before depacking, and from what I can see it uses a decryption key it fetches from the keyboard CPU. It doesn't seem to be correctly emulated though. What's the current status of 6301 emulation in Hatari?

regards,

Troed
