Yeah, just like his Dracula X dub patch: distribution is a zip archive with a batch file, etc. It'd work something like this:
1) Use TurboRip to rip an ISO/WAV/CUE image file set from your Ys IV disc or get an image from someone else.
2) Download the text patch, unzip in same folder as image file set, double click "PATCH.BAT" - (This step not needed if already text-patched!)
3) Download the dub patch, same thing...
4) Burn CUE to a CD-R to play on real NEC hardware, or, mount CUE with a virtual disc emulator to play with a NEC emulator.
*For now, yeah, I decided to keep my text patch separate from the dub patch. So you'll have to run 2 batch files. When I get around to making a new patch with all the minor text edits like 'Romn' to 'Romun' in the future, then we'll have one Windows based patcher that does it all!
*Since most of you already have an Ys IV image that's patched textually, you could just rip that instead of an original and just use the dub patch which I think most will be doing... Will work either way, with or without an extra step.)
*There are crazed Japanophiles that don't want the dub patch, believe it or not! They can burn in... eh, nevermind! Heh-heh!
