@KingMike/dACE/elmer - Thanks a ton everyone. I haven't gotten this working yet but I have tried a bunch of things.
You can also find those "cmdtools" here: https://github.com/RDCH106/ECM/releases
- i do use Mac but I also noticed that the links for the windows .zip file wasn't working on the archive.org page (the mac ones were, oddly) so you can grab them from github instead
My issue at this time will be extracting that data "track2.iso" from the larger image.
I have a few images from the internet that all run 100% perfectly fine in an emulator but they aren't broken out into data/audio files, they are just CUE/BIN, CUE/ISO and also CCD/IMG
Unfortunately all of my software also thinks that these are audio format images (2352), also known as Mode 2 discs. Apparently they are expecting Mode 1 (2048) disc images. I need a way now to break out the "data track2.iso" from the other audio tracks and then work with that one. Otherwise the offsets that I have will not correspond appropriately.
I will also reach out to the individual who submitted that hack, MooZ, on his own site's forum to see if he can help me out with this as well.
As a side note: this game actually is quite nice, its the "ladies" version of the great tennis game on the PCE.
Addendum: I can certainly obtain a copy of this game for a very reasonable price from Japan as well. I will be over there later this winter and I know this game is not expensive at all.
