1.60a causes crashes in pop'n UniLab, Jam&Fizz, possibly more #8
Description
1.60a contains a regression that causes crashes on startup in some games. I was only able to test this on pop'n music UniLab and Jam&Fizz, but I asked others and they were able to reproduce it on Jam&Fizz. This issue was not present in 1.50d. This may affect more games (most likely other versions of pop'n), but I don't have access to any of them to test.
The games will pass their hardware tests fine, but then crash after a brief moment of "now checking network data".
Without an appropriate plugin loaded, the games did not crash immediately (although they did crash when attempting to do anything that needed the server, such as scanning a card or finishing a credit). Keep that in mind when trying to reproduce.

Without further informations we can't identify what the problem is. Since 1.60a mainly only remove profile limits and does not touch other communication part of the code.
Please provide:

Unfortunately dev mode doesn't seem to help here, it fails to load the pop'n plugin under dev mode. It loads just fine without dev mode, it's specifically dev mode that doesn't work. A different crash happens with no plugin (which I assume is normal) where the game boots but crashes at the end of a credit or when scanning your card, so the spice logs will be without the server in dev mode.
The plugin used is from https://github.com/cracrayol/plugins as that version adds Jam&Fizz support. It works without issues on 1.50d, which is what led me to believe it's not a plugin issue.

Do you have node install on your system? If so, run
npm iunder plugin folder and try again.shny-scott commentedon Feb 28, 2026
I tried running npm, but it wasn't installed. Didn't have the time to look into it last night and I'll be away from my desktop for a couple hours today. Not sure what node version it needs, if it's latest or one of the LTS releases.

Installed node, ran npm, restarted in dev mode. The plugin loads, but nothing special seems to happen.
I tried running 1.50d in dev mode out of curiosity, but it doesn't print anything to the console either. Game just doesn't crash.

People seem to suspect that this is caused by #3 but it only affects the popn plugin.

Hmm, that's interesting, does popn check anything facility related?

Reproduced in RB (all titles).
Game crashed during Now Loading stage 3.
Game can skip loading state when bypass "pcb.rb6_pcb_boot" method, it ultimately crashed at demostration scene.
Not sure if I can fix that in plugin for now.

This is a HUGE info for fixing this, I will take a look into this
dannylin0711 commentedon Mar 11, 2026
I might need stacktrace to see what actually happened...
Might go for a full game startup to see...
dannylin0711 commentedon Mar 12, 2026
#9 Probably fixed lol
The region code is not confront to konmai structure thus the game does not want to boot.
RoxCian commentedon Mar 22, 2026
Thank you. RB is alright now.

Thanks for the report, I will close the issue once I know other games are working fine
