After doing source code diffs with Zaphod’s original gpSP port and zacaj’s later port, I did a full and proper re-port of the Exophase’s latest version of gpSP. My build uses iPod-specific code rewritten based on Zaphod’s changes and the iBoy source code and adds many features that can improve usage or offer emulation speed-ups.
There are two versions: one with sound and one without sound. It is recommended that you use the binary without sound as it is faster (and sound quality is very choppy anyway). The download also includes the iPod-specific source code, which can be also adapted in the future for porting other emulators).
For installation and usage information, read the “ReadMe from Keripo.txt” file in the download. For information on gpSP itself, read the documents in the “doc” folder. Other than that, enjoy and leave your results/feedback here!
