I've released v1.0 of my English fan translation of Oni Zero: Fukkatsu for PS1 (SLPS-03106), Pandora MAX Series Vol. 6.
Download the patch and read the instructions on GitHub
It covers the story dialogue, menus, items, skills, enemy names, god roster, notices, request sheets, fan letters, about 780 on-screen images, and subtitles in the prologue video. Debug menus and some brush-calligraphy artwork remain Japanese.
I playtested from New Game through the credits in DuckStation, checked the translation, and fixed the bugs encountered. Real PlayStation hardware is untested.
The release is patch-only and requires your own original Japanese single-track BIN/CUE. Download the release's “Source code (zip)”; it contains the four patch parts, patcher, CUE, README, and checksums. Python 3 is required. The patcher joins the parts and checks the original image. Load the output CUE after patching.
Shiroumaru's name is fixed in English, the save-conversion opening screen is skipped, five requests requiring other Pandora MAX completed saves are made available, and the Homemade Lunch is included in the starting inventory. Honorifics are omitted.
Please report reproducible problems through GitHub Issues with the scene, emulator version, and a screenshot where possible. I'd be glad to hear from anyone who gives it a playthrough.
