BIOS transplant from Debugging Station (DTL-H1000) to consumer PSX

Post by redwine70 » October 11th, 2021, 8:13 am

Hello, would it be possible to transplant the DTL-H1000 BIOS to a consumer PSX?
If I read correctly the DTL-H1000 could read mastered discs and did not enforce region lock.
So would there be advantages for the consumer user?
Thanks for any information.

You can but it would not make any difference. Its not the BIOS that enforces the region lock.

You don't want to swap the BIOS. You want the HC05. That's where the security is, but don't do that because there is no point. Just use a modchip. You'll ruin a DTL-H1000 for nothing by swapping it.
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.
