RetroArch JAXE Core for XO-CHIP, S-CHIP and CHIP-8: Feature Support Guide

JAXE is the XO-CHIP/S-CHIP/CHIP-8 core for RetroArch, described in the official documentation as a fully-featured, cross-platform emulator written in C. The document also marks the core as a work in progress. This guide summarizes the documented feature-support status so you know which RetroArch capabilities the core reports as available before you configure it.

Features documented as supported

• Per the official feature table, JAXE supports the following RetroArch features:
• - Restart
• - Screenshots
• - Saves
• - Save states
• - Rewind
• - Core Options
• - RetroArch Cheats
• - Controls
• - Remapping
• - Rumble
• - Softpatching

Features documented as unsupported

• The same table marks these features as not supported by JAXE:
• - Netplay
• - Memory Monitoring (achievements)
• - Native Cheats
• - Multi-Mouse
• - Sensors
• - Camera
• - Location
• - Subsystem
• - Disk Control
• - Username
• - Crop Overscan (in RetroArch's Video settings)

What the feature status means for your setup

Because Netplay is listed as unsupported, the core's documented scope does not include networked multi-player sessions. Memory Monitoring for achievements is also listed as unsupported. Native cheat formats are not supported, though RetroArch's own cheat feature is. Persistent saves and save states are documented as supported, so state-based workflows within RetroArch remain within the core's documented scope.

Controls and remapping are both documented as supported, meaning input configuration occurs through RetroArch's standard control and remapping features. Rumble and Softpatching are likewise listed as supported. Features tied to peripherals or multi-user setups — Multi-Mouse, Sensors, Camera, Location, Subsystem, Disk Control and Username — are documented as unavailable, which is consistent with CHIP-8 style software that does not use them.
