Need help with modchips
No need to install a modchip, you can use freepsxboot: https://github.com/brad-lin/FreePSXBoot/

Any way to recover Memory Card data?
If you your PlayStation doesn't have a modchip you can also use the Memory Card manager in Unirom. Just get the FreePSXBoot version into a different memory card, boot to Unirom and the manager will show all saves, even the deleted ones, if they are still on the card. Then you can put the cursor over them and choose "undelete".

I have 80+ PS1 bootlegs from the early 2000s and need help (more in comments)
you could use FreePSXBoot to softmod it, here’s the github.

how does region lock work?
If you don't want to chip your console just get a Memory Card exploit like Unirom+FreePSXBoot or TonyHax+FreePSXBoot, it's basically the modern day replacement for the swap trick. Easier, more reliable and removes some other types of piracy protection from various games.

Ask HN: What weird technical scene are you fond/part of?
Most of the SDK has been tested and confirmed to be fully functional on real hardware, but there is some copy protection you will have to get around in order to run arbitrary software on a PS1. The traditional solution is to perform disc swapping or install a modchip, but nowadays we also have softmods [1] that make the process as easy as inserting a specially formatted memory card (which can be prepared using a PS2, or even a PS1 by swapping discs).
You are not required to use CDs either. With the help of some code and linker script magic, you can build an image that can be booted directly from a cheat cartridge (or simply a parallel EEPROM) connected to the console's expansion bus, bypassing the copy protection checks entirely. There are also debugging tools that, once loaded, let you download an executable into RAM for quick testing and manage memory cards using a modified serial cable [2].

multi_rx,py example for decoding multiple voice channels on single rtlsdr
looks like it may not be able to do what I want it to do according to this. https://github.com/boatbod/op25/issues/184

How can we convert a DMR signal into clear voice by RTL_SDR?
I have no experience with DMR myself, but my understanding is that the Boatbod fork of OP25 has experimental DMR support, and I believe SDRTrunk software does, too.

Ask HN: What weird technical scene are you fond/part of?
Using OP25[1] with RTL-SDR dongles to implement scanners for trunking P25 radio systems on a computer. And as a sidebar to that, listening in on geographically remote public safety radio systems using Broadcastify[2]. It's basically the old "radio scanner" culture, but taken online and distributed worldwide. People listen to all sorts of stuff, but given my background as a former firefighter and former 911 dispatcher, my main interest is listening to public safety dispatch stuff.
That said, another commenter below mentioned modern "phreaking" and how it's become more radio centric... and while I won't admit to doing anything illegal, let's just say that there's some interesting stuff you can do / look at / listen to these days, especially with ubiquitous and inexpensive SDR hardware and related resources. See the recent story about the KrakenSDR passive radar stuff, and some of the papers that are out there about P25 security flaws, some of the automobile hacking stuff that's RF based, etc., etc. There's a fascinating world out there buzzing around on invisible electromagnetic fields... and you can tap into it with a $30 dongle and a Raspberry Pi (or your PC).

Is this encryption or frequency hopping or just not FM modulation? Not law enforcement, just a school they use Motorola handhelds.
If it's P25 Phase I or Phase II then SDRTrunk might work. boatbod's op25 might be another option, but more complicated to set up.

Using a Raspberry Pi without a GUI to stream scanner audio to a phone
I don't have a full guide for you, but I use https://github.com/boatbod/op25 for receiving and decoding P25 Phase 1 digital signals on the command line.

How can I hear the Franconia, VA (Fairfax Co) Police, Fire, EMS scans? Unsure if there is a specific open mhz link for them. Thanks!
If you are handy with Linux you can use an RTL-SDR and OP25 on a Raspberry Pi or really any PC. This is the page for the Fairfax trunked system https://www.radioreference.com/apps/db/?sid=6957. Any talkgroup with mode D can be listened to, mode DE is encrypted. If you want I already have config files made up for the police dispatch and fire/ems dispatch channels.
