JGR Portable - Beta 1 (v1.0.2)

JGR Portable 1.0.2 improves startup and fixes hidden files interfering with asset preparation.

• The game starts directly and loads the asset preparer as a temporary module only when needed. The converter unloads before gameplay, releasing its memory.
• PSP and browser preparation ignore filenames beginning with a dot, including macOS metadata files that could be mistaken for a second GDI.
• Retains the Windows asset-manifest filename fix from 1.0.1.

Download JGR_PORTABLE-1.0.2.zip for EBOOT.PBP, Prepare 1.0.2.html, README.md, and LICENSES.txt. The executable and browser conversion code are identical to the latest 1.0.2 test build.

Updating from 1.0.1 or a 1.0.2 test build: Replace only EBOOT.PBP in PSP/GAME/JGR_PORTABLE/. Keep your existing data folder and saves. For fresh preparation, use the EBOOT and Prepare 1.0.2.html from this package together; the 1.0.1 preparer cannot read the new application bundle.

Requires your own Dreamcast USA MK-51058, V1.005 disc image in GDI format with all referenced tracks. Original game assets are not included. Extract the package and follow its README.
