Poorman's Usbloader

[Type 79]

Hardware:

• - Action Replay cartridge (any cart with X-Flash supported eeprom should work)
  - Link-Cable (half)
  - USB To RS232 TTL CH340 Auto Converter Module from ebay
  - Level Conversion Module 5-3v from ebay
  - (usb connector desoldered, usb-cable from old mouse, small box)

Software:

• - ROMProd 0.2 by sicklebrick
  - Serial version 1.3 by Jihad (PSXPAL.EXE or PSXNTSC.EXE)
  - PSXSERIAL V1.0 by Shadow
  - X-FLASH V1.2 BETA 3 by FIREFLY

Rom created from ROMProd & PSXPAL.EXE. PSXSERIAL V1.0 is too big to fit in 128KB cartridge.
For uploading I use PSXSERIAL.

Instaboot, power on PlayStation and it's ready to receive.
Windows 8/7 compatible, just plug-in usb and check COMport-number from Device Manager.

Requirements:

• - PlayStation with Parallel I/O port (SCPH-100x - SCPH-750x)
  - For flashing: Someway to boot from X-Flash cd (modchip, swaptrick, cart with cdstop (Ahoy! 0.34))

I wonder if 0-5 volts logic is safe for the PSX because I happen to have a CH340 clone (disguised as a USB-RS232 cable) which outputs 0-5 volts logic.

Well, no smoke so far, but maybe I should add something like this in.

First post updated.
- Level Conversion Module.

ToDo:
Internalize, say no to linkcable butchering.

You can also do this with a 74HC244, with no extra components.. If you are just using HITSERIAL just wire up txd/rxd gnd and +3.3v.. they cost around £0.50 each..

do i need a ch340 or a FTDI FT232bm? im a bit confused, are the same or not?

[danhans42]

Either! You just need a +3.3v UART. They both do the same thing..
