NRoach44's notepad

Having built my previous Dial-Up system, I decided to try integrating all the components into one system. The journey to get one of the components working lead me to making my first jailbreak.

The Sony PSX was exclusively sold in Japan. Naturally, they didn't bother with universal power supplies since that'd add cost.

Based on the work of "Lonedone" on the Assembler games forum, we knew that the power supply of a PSX2 (DESR-x500 or DESR-x700) could be upgraded, but now I've tested …

I wanted to see if the NABU PC's power supply could be modified to work with 230V, so I traced out the schematics. After doing all that, I looked up the switching transistor and found it'll only handle 230VDC, which is way too small. So here's my partially traced stuff …

The Sony PlayStation 2 originally launched in Japan first. The first three models are exclusive to Japan, and thus only have 100V capable power supplies.

This is for Single Density systems, the disk size and format in cpmtools / greaseweazle will need to be changed for DD models.

Create a file that's the right size (100K):

$ dd if=/dev/zero bs=1024 count=100 of=occ1sd.img

Create a CPM file system on the disk:

$ mkfs …

If you're feeling adventurous, combine the two hex files, and convert that into a binary:

$ cat cpsker.hex cpvosb.hex > kerm411.hex
$ hex2bin kerm411.hex …

For some reason, my main admin account would lost admin rights every time jellyfin restarted.

Firstly, grab your user account's GUID:

sqlite3 /var/lib/jellyfin/data/jellyfin.db "select id from users where username='REPLACE';"

Then, the following fixed it:

• nano /etc/jellyfix.bash

#!/bin/bash
set -e
