To quote from Jabu on SATURN-FPKG v1.1:
How to use it:
- Run SATURN-FPKG.exe
- Select a CUE file of your Saturn game in "Disc"
- Customize some settings (you can change the icon, ram cartridge, game title etc)
- Input a unique NP Title (auto game id detection coming soon!) or press the "Random NP Title" button
- Click "Create fPKG" and choose a storage location
- Install the created fPKG on your PS4 and play
- ISOs are probably not supported by the emulator and won't work (use proper CUE/BIN game images!)
- A uniqe npTitle based on the game product id will be now automatically selected
- You can righ-click on a text box to reset it's value
- You can select which RAM cartridge should be used for a game (eg Street Fighter Zero 3 uses the 4MB cart for better animations) but most games should run fine on the default setting
- You can hide the in-game "Press Options for Options" box by checking the "Hide Options Box" checkbox.
- When playing a game press the touchpad or hold the Options button for a settings menu, you can change some display options and button configs there, you can also quick save/load/rewind the game there.
- Works only on fw 9.00, backporting needs be done to older fw's, if anyone backports this emulator to older fw's please let me know, I'll include them in an update.
- Savestates won't work when a 4MB RAM cartridge is used.
- Custom Borders in .png format will get corrupted if they're bigger than ~1MB, gonna try to fix it soon (I need to figure out how the tex header works first)
Thanks to k6stor for support.
