一项开源项目公开发布了对M-VAVE FM-1口袋合成器固件的逆向工程研究成果1。该项目在GitHub上详细记录了这款设备的硬件架构，确认其采用JieLi AC791N/WL82芯片和pi32v2 CPU1，XIP flash地址位于0x020000001。
项目研究者对该合成器的六运算符FM引擎进行了分析，发现其基于Dexed/msfa派生设计1。为便于进一步研究，团队发布了多项调试工具，包括USB-MIDI更新协议客户端、Ghidra脚本和OTA加载器提取工具1。
值得注意的是，项目明确声明"主分支故意不包含替代固件或自定义固件构建器"1。研究团队同时警告称，更新协议尚未被证明为可靠的恢复机制，当前工作还未建立ROM恢复、回滚或安全中断写入行为1。
An open-source project has completed a comprehensive reverse engineering analysis of the M-VAVE FM-1 pocket synthesizer, mapping the device's internal architecture and publishing detailed technical documentation on GitHub 1. The effort identified that the synthesizer uses a JieLi AC791N/WL82 chipset with a pi32v2 CPU, and contains a six-operator FM synthesis engine derived from Dexed and msfa 1. The project includes XIP flash memory mapped at address 0x02000000 1.
The research release encompasses hardware architecture mappings, OTA protocol analysis, firmware decomposition, and debugging tools, along with a USB-MIDI update protocol client, Ghidra scripts, and OTA loader extraction utilities 1. However, the developers have explicitly stated that the main branch "intentionally contains no replacement firmware or custom image builders" 1. Additionally, they caution that "the update protocol is not a demonstrated recovery mechanism" and that "current work has not established ROM recovery, rollback, or safe interrupted-write behavior" 1, underscoring the experimental nature of the tools provided.
