Got my hands on a 500D and thought I'd try dumping the 1.1.2 firmware but ran into this:



Same issue with 1.1.1. I have used the portable dumper a few times and have never seen this before.

Old-style model; covered in first post.

The good old blind dumper appears to work in QEMU (should work on all D4 and D5 models with bootflag enabled, except 7D). Make sure you have a valid image on the card, then go to PLAY mode. Split the dump in two, like you did on M2.

Well that does look similar to what we were doing a year ago. Tried the "blind dumper" and it gave me a file named "As" that was apparently the ROM1.BIN and didn't need to be split. Disassembled it and it looks good.

Thanks again!
