It keeps reading the opcode following the HALT after its first execution.

Re: How long can an interrupt be blocked?
32T on 48K, 36T on 128K, 32T on +2A/+3. Might be +/-1T from those based on temperature. The early or late timings issues. Not my speciality!

Re: Renegade 128k slow music
There's no in-game music on SpecEmu or ZX Spin for the +2A/+3 machines but the title screen music plays at normal speed. Title screen and in-game music plays at normal speed for the 128/+2 machines on both the emulators.

Re: New release of SpecEmu
So apparently there's probably some bug affecting the Pac-Man option since there was some Pac-Man-related April Fool's code this year if you had the game ROMs installed or something.

Btw, Pac-man is still there for me in the Tools menu in the latest version. No idea what might've changed for anyone else.

Re: ZEsarUX 10.3
This reason why some emulators just reset with that disk is because they don't do: "On the ZX Spectrum 128 and ZX Spectrum +2, reading from BFFDh will return the floating bus value as normal for unattached ports, but on the ZX Spectrum +2A, +3, +2B, and +3B machines, it will return the same as ...

Re: ZEsarUX 10.3
Another program is Plus-3-Mate, but it crashes everywhere except on SpecEmu, which unfortunatelly treats eDSK files as read only. I'm sure it was something related to the AY chip on a +3 and how it differs slightly from the 128/+2 that causes that crash/reset. The details are probably on the WoS fo...

Re: Inkspector 2.0.5 available
Thanks for marking my work :D I suspect this is the same issue that causes a single column in the Shock megademo on a 128k to show incorrectly (I deliberately broke it in 2.0.4 to fix a game that wouldn't start - see the release notes). It's on the todo list for 2.0.6 to fix anyway. BTW what is tha...

Re: SpecEmu: Command Parser reference?
The command parser has an "asm <opcode>" command if pasmo.exe is in Specemu's folder. It assembles to the address at the top of the disassembly window for quick patching of code.
