ChisFlash V0.1 Youth Edition Open Source GBA Flashcart

The functionality is the same as ChisFlashV1.0.
ChisFlash V0.1 (Pichu) uses 256Mbit Flash and 1Mbit SRAM, compatible with 99% of GBA games, and supports NDS and GBcartRW burning.
Important notes:
When making the PCB, ensure the thickness is 0.8mm.
The FM28V100-TG in the BOM should be the same packaged SRAM. Specific selection will be updated in real-time within the group.
Currently in beta testing, the firmware needs to be obtained from the QQ group (chisflashlitx_xxx.pof). After beta testing is complete, the firmware code will be open-sourced on GitHub.
