I tried playing Ape Escape on the 11/24 nightly, and for some reason, up and down on the right stick are reversed. (N3DS .CIA) Any way that I can fix that?

Seems like it. My November 19th build of CatSFC works fine with DKC. Generally, graphic corruption is at the fault of the ROM, not the emulator.

It actually ran just fine before. Glitching started in the builds since a few weeks. If I take an older build, the glitching is gone - but that build won't run at proper speed because it doesn't use the right code to run at full N3DS speed (which hax 2.5 requires). It's the PAL rom by the way, perhaps that's why you're not having the same issue (you're running NTSC rom is my guess)

Indeed, NTSC rom here.
Also, it is usually full speed on my end (New *hax2.5). Eh, maybe I'm just getting the better end of the stick.
Are the piggybacking cores (FBA and MAME) still being troublesome, by the way?

Hi. I need help with mame.

When I start MAME2000 or 2003, I always get to choose an application (download play), then it freezes.

I have a N3ds 9.0. Cps1 works fine. And neogeo too.

It's asking you to choose a title, not making you choose Download Play. Use the 3DS D-Pad to cycle through titles to run with. These large cores need to run under another title with large enough segments to fit their code.

The problem you'll face is that it's only a handful of titles that these cores are able to run under successfully. Super Smash Bros., Monster Hunter 4 and the latest version of YouTube are the known-working titles. Monster Hunter 3 likely to be another good option, but won't be selected automatically. If you have any of those earlier listed titles, these cores will run under those immediately, it's only if you don't have any that you hit the manual title selector. If you happen to have any of those on a cartridge, you could try putting them in before you play.

If you don't have any of those games, you'll just have to either download one (demos work, too) from the eShop if you still have access, find something else you have that will fit the RetroArch cores (e.g. by trial and error) or go out and buy one of them on cartridge.

There is also a second issue with those cores currently as discussed recently in this thread, but you can deal with that one once you get to it.

EDIT:

they are, I still didn't come up with a solution, in the meantime, you should be able to start them by using a shortcut with a valid rom path.

This is true, but complicated somewhat by the fact that reentrant loading is broken in MAME 2000. Users will need to create one shortcut per ROM for MAME 2000 currently.

How would one do this?
Click to expand...
Here's what I did personally.
  1. Move all affected cores to a new directory so that they're no longer shown in the list. (I used /3ds/cromulent/)
  2. Select a small ROM from my collection to use as the default loaded ROM (keeping in mind that you'll have to wait for your selected ROM to load before you can start using the core).
  3. Create XML shortcuts for all three cores (see spoilers below) using my selected ROMs.
  4. Place these XMLs in /3ds
This way, the shortcuts appear in the list, taking the place of the full (non-working) cores.
Code: 
<shortcut>
    <executable>/3ds/cromulent/fb_alpha_libretro/fb_alpha_libretro.3dsx</executable>
    <icon>/3ds/cromulent/fb_alpha_libretro/fb_alpha_libretro.smdh</icon>

Again, keep in mind that MAME 2000 only allows loading one ROM at a time, so if you want to load more than one game you'll need to create more shortcuts.

Edit. I tried with smash bros, and appears this:


Retroarch info: does not have enough samples for monitor refresh...... Requires at least 4096 frames.

That sounds like you're hitting up against the second issue with these cores that I mentioned. Ever since support was added for games to be loaded automatically on startup, these cores haven't worked standalone because they try to run a non-existent game. aliaspider is working on this, but in the meantime the recommendation is to run them via shortcuts instead, specifying a (correct) ROM for the core to run instead of the erroneous one it's receiving currently.

I described the process for getting this working in the second half of the post where I replied to you, after the edit.

I hope that the Retroarch menu gets moved to the bottom screen soon, and also for the addition of photo images on the bottom screen for specific roms, similar to M2's (3D) Sega Genesis/Mega Drive emulator.

PCSX ReARMed crashes now when i load a .img file, fps jumpes between 9 to 15 and inbetween before crash

EDIT: N3ds ironhax .3dsx

EDIT 2: tested several other emulators of the pack, and they all crash after several seconds to a minute or 2. nes/snes/pcsx/gbc/gba

Edit 3: fixed it, just needed to reinstall retroarch.
