CH32H417 looks interesting. It has the UHSIF interface which can handle 32-bit transfers at 125Mhz (much more than ~37Mhz of IOP!), and also has 5Gbps USB with PHY, Ethernet 100M PHY integrated (with RGMII support for MAC 1000M), RTC, and SDIO host.

Some notes on EE kernel upper bounds: Kernel entrypoint 0x80001000 -> ee_deci2_manager_init -> deci2_reg_cmd_handlers (after printf) -> deci2_cmd_handler_80016660 (ID -> 0x21F?) -> deci2call_exrecv_80011ED0 2nd argument before bitwise or 0x8003b630 + 128 buf size Reference...

The netman implementation in ps2sdk can already group and DMA transfer multiple packets to the EE.

The FSMC functionality of CH32F203, CH32F205, CH32V303, and CH32V307 looks interesting. Full speed (~37Mhz) half duplex 32-bit SSBUSC transfers might be possible with some additional hardware to multiplex the address/data lines. It can run at up to 144Mhz, has Gigabit Ethernet MAC (with 10M/upto...

The SBIOS implementation in osdboot is relocatable and no longer at a fixed position. Also, the information structure passed to the kernel is also relocatable and contains the pointer to the SBIOS implementation.

And looks like we're back! Some things of note: ps2dev now has tagged v2.0.0. (Scheduled releases would be nice) DESR firmware works in https://github.com/Florin9doi/pcsx2/commits/magicgate_2026/ BIOS: "DESR v02.10.bin" Network & HDD: Hard Disk Drive [x] Enabled / HDD File...

DVRP firmware does not handle ATA command 0x80.

FILEIO 1300 -> 1500 changed end buffer sizes from 16 bytes to 64 bytes (RPC not backwards compatible). FILEIO 1500 -> 2100 added new APIs. FILEIO 2100 -> 2200 did some major changes and started using multi threading and SIFCMD for sending results to EE (RPC not backwards compatible). FILEIO 2200...
