It's great that you are still recreating this project. It will be very interesting to know the results of all these works.

Are you writing the code for it? The schematic needed to be updated too so I hope you know what you're doing with it otherwise you're wasting time/money
Development Console: SCPH-5502 with 8MB RAM, MM3 Modchip, PAL 60 Colour Modification (for NTSC), PSIO Switch Board, DB-9 breakout headers for both RGB and Serial output and an Xplorer with CAETLA 0.34.
PlayStation Development PC: Windows 98 SE, Pentium 3 at 400MHz, 128MB SDRAM, DTL-H2000, DTL-H2010, DTL-H201A, DTL-S2020 (with 4GB SCSI-2 HDD), 21" Sony G420, CD-R burner, 3.25" and 5.25" Floppy Diskette Drives, ZIP 100 Diskette Drive and an IBM Model M keyboard.

"It was worth a try once no ?"
I did it once.. and it won't work with regular XP/PAR.rom
"you're wasting time/money"
Probably yes, but we now know it doesn't work..
Like you said..Except if :
"It needs a lot of programming to get it to work as intended"

I can confirm that the PSX Blaster design doesn't work.
I simulated the logic in a software and it is wrong, RD_USB goes low require AD17 AND !AD17, which is impossible.
Also, the logic voltage are mixed up, some logic chip have 5V, some other 3.5V, and the USB chip receive 5V logic on its pin where VCCIO is tied up to 3.5V.
I made the board and apart from the ROM booting (I used n00brom for testing), the USB chip is not recognized and the logic signal are bad (can't make RD_USB low at all)
I'm planing on making a new working cartridge for dev (like an xplorer cart but using USB)
