This is a series of IPS patches for Neo Geo Pocket games that unlock content in the game. I made these patches after noticing some discussion about wanting to use them on flash carts and realizing the collections on steam discounts. (I mean how it includes two player modes) :)

Q. What do these ips patches do?
a. When applied, it unlocks as much content as the game has to offer while maintaining minimum factory default settings. So no records are recorded unless necessary.

Q. How do I use these patches?
a. Simply use a IPS patcher on clean roms. You can verify your "clean dumps" by comparing the crc-32 hashes with the ones on the dat-o-matic website. I recommend Flips and buying Neo Geo Pocket Color Selection on Steam for clean dumps. Install the collction, look in the game's folder, then data>game>SNK>NGPC. This is what I used to create the patches and test it. But I assume any patcher including online browser patchers will work. (Should be safe to use on translation patches. It's only meant to alter save data, not game programming)

Q. What's the difference in the two folders?
a. The rom patches are for roms. You can use these on real neo geo pocket color with flash drives or any emulator with the exception of Neo Geo Pocket Selection by code mystics. Their emulator WILL NOT boot any modified roms, so save patches specifically made for their save data will work. In case of other emulators, rom patches will work with no issue. 

Keep in mind how some emulators will handle saves. Neopop or emulators based off it will save data to seperate file. Unlike the code mystics emulator that create save data inflated and padded with nonsense, Neopop saves only what is necessary making them much smaller. The rom remains unmodified, so any time the patched rom doesn't detect save data file, it will default to unlocking everything before creating new save data. ares is the only emulator I know that stores the save data in the rom file (Just like a real neo geo pocket cart and flash drive) probably making that one the most accurate emulator. So it may need repatching if the rom is lost.

Q. Why should I use these patches?
a. It's your choice. Some games have content that is unlocked in more than one way. SNK VS Capcom for example allows users to link their neo geo pocket to a real dreamcast and copy of the Capcom vs SNK, King of Fighters 1999 Dream match, or even SNK VS Capcom card fighters clash game to help unlock characters faster than not using those. Without those (Which includes majority of players either using real neo geo with no link cable or emulators including collection by code mystics) will be require to spend much more time to unlock all content. Beating story mode constantly to unlock characters and olympic mode to unlock their stronges super combos. Simple comparison is probably super smash bros, player can choose to fufil special conditions or accumlate lots of play time in versus mode.

Using this patch just unlocks everything so you don't have to the hard way. So people just wanting to enjoy the game for fun can from the start. I also should point out the collection by code mystics include versus modes, so you can easily unlock everything for two player fun.

Q.Which games are included?
Dark arms Beast buster 1999
Fatal Fury F-contact
King of Fighters R-2
The Last Blade Beyond the Destiny
Metal Slug 1st Mission
Metal Slug 2nd Mission
Neo Turf Masters (also known as Big Tournament Golf)
Rockman Battle & Fighters * (Included In vol 2)
Samurai Shodown 2!
SNK Gals' Fighters
SNK VS Capcom The Match of the Millennium ** (Included in the switch collection, but not included with the steam collection, much purchase seperately)
Sonic The Hedgehog Pocket adventure *** (Not included as of writing. No save patch included. Consider it a bonus)

This was heavily focused on neo geo pocket selection vol 1. The save patches is intended for these collections exclusively and should work on steam and switch versions. (Switch versions will probably require modded system to access unencrypted save data. Copying save from system to SD card the normal way will not work since it's encyrpted) 

If for some reason there is more demand, or if I'm bored again... perhaps more will come. Hope this will help someone, thanks to code mystics for the exellent emulation compilation of neo geo pocket games. I honestly never tried the actual system before and it was a interesting experience. I only hope more releases will come sometime *ahem* Sonic pocket adventure. Maybe also include "Wireless multiplayer" mode on switch to make it more authentic? It was probably easier to do locally. But we are talking bout the same team that added "Rollback netcode" to other SNK games. So... Money is in our wallet, but the ball in your court code mystics. Question is how badly do they want it from us? :)
