For .gxp archive you need to use GxpPacker from [AVGEngineV2] Tools.

Drag & drop a .txt file or folder with .txt files and existed .bin files will be rewritten by new changes.

Extract exmaspaz.exe scr.dat 0 Pack exmaspaz.exe scr.dat 0 scr1.dat

It seems like mashiroext3.exe doesn't work, it doesn't crypt archive. This should work: https://github.com/regomne/chinesize/blob/master/Musica/exmaspaz/exmaspaz.exe, I tested it, but font doesn't support English chars. Upd: a game engine doesn't expect spaces in text, so you need replace it with something similar. Note: you need to replace original scr.dat, scr1.dat isn't applied by the game.

Screen of a game or of the tool?

Do you need repack only scr.dat or other files as well? Try it: https://github.com/regomne/chinesize/blob/3149d37e37c3adf1a3a898dc146d1d75709120f3/Musica/mashiroext/Release/mashiroext3.exe Source: https://github.com/regomne/chinesize/tree/master/Musica/mashiroext Warning: it rewrites supplied .dat file so make copy. The example used "scr1.dat" name. I don't know maybe the game read this file as patch.

Can you share an original packaged file to example?

Can you share any .pak file as an example?

Another way to open archive is WinRar or GARbro. You probably can pack it back if get https://store.steampowered.com/app/345370/TyranoBuilder_Visual_Novel_Studio/ Or you can try make a patch: https://steamcommunity.com/sharedfiles/filedetails/?id=1656651442

Perhaps you need to find new crud and keys for English version: https://github.com/Inori/FuckGalEngine/issues/37#issuecomment-483125640
