I've finally found some time to merge my TASScript and mouse changes into the v11.8 code base, and have created an Alpha version for what I propose will be JPC-rr v11.9. You can
download it and try it here, and I'd appreciate it if people could take it for a test run and let me know if you find any issues. Unfortunately, I know nothing about git, so I'm hoping someone else will be able to update the JPC-rr git repository with this new build.
I also looked into the Mice Maze error and unfortunately I wasn't able to fix it. On the surface it looks like for Mice Maze to work, you need to have JPC-rr be in "protected mode", but I have no idea how you'd get that going.
Another consideration in general is that JPC-rr is built off of version 1 of JPC. The latest version of JPC is v2.4, and it's likely several emulation issues have been resolved in the newest build. If someone wants to upgrade v11.9-alpha to use JPC v2.4, I think that would make a good candidate for a new major version (JPC-rr v12).
Let me know if you have any questions.
