Hello! I'm the author of the Job System Improvement hack.
EDIT: I can confirm now that it looks like my Job System hacks all work with the ChaosRush translation. I didn't compare changed offsets, but I applied my hacks and played around in the menu and all my changes were working and nothing looked out of the ordinary!
One thing to keep in mind is that the Chaos Rush translation already shows Skill Level on the Job menu. So if that part of my hack is applied you'd see duplicate values. On the other hand, if you don't use that part you'll see CP Costs that are irrelevant. lol I wouldn't mind getting together with Chaos Rush to add an optional patch for just blanking those values out.
I can confirm that so far it seems to work with Adrian's B-Button Dash and the individual patch for "Flee BugFix" from Maeson's mix, since I have those applied to my personal copy.
Also, the latest version (v2.1) includes some changes to allow players to skip the whole "remove my character's equipment before changing jobs" process by automatically removing gear when you select a job. It also removes some extra prompts and inputs and fixes an aesthetic Job menu bug, so be sure to grab the latest version. Note: I changed the hack title to reflect that it's a bit more comprehensive than just a "Free Jobs" hack.
I'm taking a few days to step away from this hack. It is my first ASM hack, and as I approached the finish line and found and eliminated bugs and tried to keep my versions straight I managed to work myself right into a bout of stress and anxiety.
Just need to find a better workflow if I'm going to keep up with ASM hacking.
Thanks for downloading these and giving them a try!
