Hmm.... not sure why that's happening. Anyone tried Snatcher with RetroArch's PicoDrive core before?
This issue affected my playthrough of Snatcher using Retroarch's Picodrive to the point that I stopped playing. I got the impression at the time that it was a known issue.
Ok gosh. That makes sense. Thanks for the input.
Will be doing a release in a few minutes from now.
--------------------- MERGED ---------------------------
v0.94 Released:
- Added support to save battery-backed RAM for CD games
- Fixed problems with games that show parts of the previous screens at the left/right edges
- Added support for cheats.
- Added configuration for region selection between (Default, US, Europe, Japan)
Thanks for all the feedback.

The emulator can save region selection for each rom. But when loading a new rom without exiting the emulator, it will continue to use the current region setting, instead of loading the saved region setting for the new rom.
It doesn't actually freeze, wait for a minute or two, I'm not sure what causes this, but i assure you it will work, I beat snatcher on my 3ds
How does the 32X emulation speed on a New 3DS compare with the Retorarch build? As a rule, with Retroarch the 2D games run full speed (including Doom) but 3D games tend to run at half speed. The Vita version is barely any better.
Ok, so I know this is a stupid question but for some reason, I'm struggling with the answer. I understand that the format should be:
bios_CD_U.bin for files that are bin+cue. For the life of me, I am unable to get this working. I know it's a naming convention that I'm struggling with so could someone dumb it all the way down for me and give me an example of formatting say "Nighttrap_CD_U.bin" into the correct syntax. Thanks in advance and thanks for making this and continuing to update such a great app.

All you have to do is make sure you have the sega cd bios files in SD:/3ds/picodrive_3ds/bios
then you should be able to play just about and sega cd game
For some reason I just can't get this to work. I've got the bios files in SD:/3ds/picodrive_3ds/bios and and named correctly from the first post. But the emulator keeps saying "Hmmm. Unable to load rom".
Could it be the game I'm trying to play? It's Mighty Morphin Power Rangers (Sega CD version). Its a .bin (& .cue) file and its 450MB.
EDIT: Nevermind. I got it to work. Renaming the bios files as in the first post doesnt work. Just putting it as "us_scd1_9210.bin" makes it work perfectly.

In regards to bubble2k’s Picodrive and the Retroarch Libretro PicoDrive;
For anyone who has tried both versions, what are your experiences with each? Does anyone prefer one over the other? Any performance differences worth mentioning?

While the N3DS is identical to the Libretro version in terms of performance, the O3DS doesn't experience the lag that the Libretro Picodrive port sometimes does.
I'm putting up v0.94b for testing for anyone who would like the latest.
Fixes include:
- Added support to save battery-backed RAM for CD games
- Fixed problems with games that show parts of the previous screens at the left/right edges
- Added support for cheats.
No emulation-related fixes, so in terms of compatibility, it should remain the same as v0.93.
Some explanation on the cheat format:
The .CHX is a cheat file format that you can create with any text editor. Each line in the file corresponds to one cheat, and is of the following format:
[Y/N],[CheatCode],[Name]
1. [Y/N] represents whether the cheat is enabled. Whenever you enable/disable it in the emulator, the .CHX cheat file will be modified to save your changes.
2. [CheatCode] must be an Genesis / Mega Drive Game Genie or Pro Action Replay cheat code. The cheat code looks like one of the following:
- **RHVA-A6WR** (Game Genie)
- **FFFE0D:0099** (Pro Action Replay)
- **FFB933:00** (Pro Action Replay)
- **FFB9 3300** (Pro Action Replay)
3. [Name] is a short name that represents this cheat. Since this will appear in the emulator, keep it short (< 30 characters).
The .CHX must have the same name as your ROM. This is an example of a .CHX file:
Filename: **Contra - Hard Corps (USA).chx**
```
N,RHVA-A6WR,Invincible
N,NNCT-AAH4,Start with 99 lives
N,H9GA-AAE6,Start with all weapons
N,AM4A-AA8C,You don't lose a weapon when you die
```
NOTE: Some games may not boot when cheat codes are enabled at the start. Disable the cheat codes when booting the games, and enable them only after the game has started.

PAR codes that begin with "FF" will NOT work on the emulators. If I save a .chx which contain " PAR codes that begin with FF ", the picodrive crashed.
it runs much better on n3ds too
star wars arcade ntsc u on N3ds is always abode 52 fps on space missions and on death star mission it runs at like 45 fps so if you use the pal version it will always run full speed almost its much better than regular retroarch that runs space missions at 30 fps at best.
there is additional glitch tough that in cock pit mode the radar has a black bar on the middle so you cant see the radar sadly this error is not presented on normal retroarch port, still very very playable.
First I want to say thanks to the creator of PicoDrive !!! HOWEVER I have a very dumb question to ask ... I have a R4 SDHC RTS LITE , most of my emulators are .NDS file extensions, this new Picodrive has a .3ds file extention, SO my question is where the hell do I copy and paste the file (.3ds) and how do I run it after ??!! THANKS 1000x in advance,

Or, I also heard that if you use flash memory, it can act as more "RAM" at least windows tell me when I stick a flash drive into it. -
