TemperPCE 3DS

Emus for 3DS (TemperPCE TurboGrafx/PC-Engine core)

This is a port of Exophase's Temper (TurboGrafx/PC-Engine) emulator to the old 3DS and old 2DS. This port heavily relies on the 3DS's 3D GPU hardware to achieve 60 FPS (or close to 60 with frame skips). Since we are using the hardware, some games that utilise special palette effects may not work so well.

This emulator bears the same user interface as VirtuaNES for 3DS and Snes9x for 3DS. It should run better on the New 3DS as usual.

Homebrew Launcher:

1. Copy temperpce_3ds.3dsx, temperpce_3ds.smdh and temperpce_3ds_top.png into the /3ds/temperpce_3ds folder on your SD card.
2. Place your ROMs inside any folder.
3. Go to your Homebrew Launcher (either via Cubic Ninja, Soundhax or other entry points) and launch the temperpce_3ds emulator.

CIA Version:

1. Use your favorite CIA installer to install temperpce_3ds.cia into your CFW. You can also use FBI to download from TitleDB.
2. Place your ROMs inside any folder.
3. Copy temperpce_3ds_top.png to ROOT of your SD card.
4. Exit your CIA installer and go to your CFW's home screen to launch the app.

CD-ROM BIOS

1. If you have the CD ROM BIOS, place them in the /3ds/temperpce_3ds/syscards folder.
2. They must be named:
   • syscard1.pce (version 1),
   • syscard2.pce (version 2),
   • syscard3.pce (version 3), or
   • games_express.pce (for Games Express).
3. You can have all four in the /3ds/temperpce_3ds/syscards folder. In the settings screen, you can choose which ROM version you want to use.

When in-game,

1. Tap the bottom screen for the menu.
2. Use Up/Down to choose option, and A to confirm. (Hold down X while pressing Up/Down to Page Up/Page Down)
3. Use Left/Right to change between ROM selection and emulator options.
4. You can quit the emulator to your homebrew launcher / your CFW's home screen.

Change History

v1.02

• Fixed the sound lag problem.

v1.01

• Fixed a crashing bug that happens if there are too many ROMs in the list.
• Fixed text description in the BIOS picker.

v1.00

• Fixes Castlevania Rondo of Blood's flickering sprite problem.
• Added support for the 6 SGX games.
• Fixed critical emulation bugs with certain instructions in the original (slow) and fast cores. Games like Populous, Choujikuu Yousai Macross 2036, Alshark, Strip Fighter, Monster Lair that used to encounter ARM 11 exceptions or freeze the emulator should now work.
• Default the CPU core to use the Fast core, which is now more stable than before.
• Added key mappings for fast-forwarding (limited to 180 fps), opening emulator menu.
• Updated button configurations to allow you to map a single 3DS key to multiple Turbografx keys.
• Minor optimizations for ADPCM and CD sound generation.
• Added ADPCM sample interpolation.
• Added feature to display battery level in the menu, and fixed some menu bugs.
• Fixed issues with games that do mid-frame palette changes. Games like Castlevania Rondo of Blood (2nd stage) and Strip Fighter look correct now.
• Optimized the configuration file read/write engine.
• Fixed bug to allow non-CD games to also save to battery RAM.
• Fixed file pointer leaks that previously caused the emulator to freeze when too many CDROM games are loaded in a single session.
• Fixed race condition that occassionally causes the sound to stop playing when resuming a game from the pause menu.

v0.91

• Fixed frame rate issues with CD-ROM games speeding up to 100-200 FPS.
• Fixed skipping CD music
• Improved overall CD/ADPCM synchronization.
• Added option to select optimized CPU core (less compatible)

v0.90

• First release.
