CTRX 3DS is a POC PS1 emulator written from the ground up. It is built using nextvolume's PSXSDK.

It is more of a research and development project and only supports some of the most basic of PS1 homebrews (HSF/ISO).

Installation

Included in the release is a freeware BIOS replacement; this is necessary to use the emulator as other BIOS aren't designed with CTRX's current state in mind.

Also include's nextvolume's puzzle example from PSXSDK.

Screenshots

Known issues

Ready to be shown as a bare-bones proof-of-concept however it is missing many core functions.
