Minor update to U-235 Disassembler

A new version of the Disassembler has been made available, there are only some minor improvements here.  The project that this was being developed for has been put on hold due to other commitments, however I have pushed this to release as it resolves a bug that was raised indicating an error with JRISC GPU pack/unpack instructions.  This build resolves that issue.

If you are using this disassembler against Jaguar RISC GPU code, I would recommend you update to the latest version.

Details of other changes are in the changelog.

(Want this for another platform other than Windows? if so, please let us know)

RISC Disassembler

We have just made available a little tool that has been in the works for the last few weeks.  It’s by no means perfect but has served us well in our endeavours so far.

We are pleased to present to you, the U-235 Disassembler.  A simple disassembler that understands the Atari Jaguar RISC cores, and can even scan through a binary and locate possible locations for RISC code within it!  Handy if you are trying to find where your code has ended up in that 4MB binary.

In addition to the Jaguar RISCs there is also limited support for MIPS R3000 code too, the output from this is missing a significant number of Op-Codes and is more likely to be at this time not 100% syntactical correct code, but it’s has already proven useful.

If you are interested in this tool it is available to download here.
