PCEAdvance is a PC-Engine/TurboGrafx-16 emulator for the GBA, it can also emulate some of the CD-ROM games, and Super CD-ROM if you've got an EZ3 card.

The main program is a windows-injector, used to inject PC Engine ROMS into the provided .gba file.

It was presented in the GBAX 2003 Coding Competition (Runners Up).

User guide

Menu options:

HScroll - (Manual) Lets you scroll the screen with the L & R buttons.
Unscaled modes - L & R buttons scroll the screen up and down.
Scaled modes - Press L+SELECT to adjust the background.
Sound - Off, On and On(Mixer).
TimerIRQ - Some games use the TimerIRQ to play sounds and music, by dissabling the timer you can make some games faster.
EWRAM speed - Don't use.
Speed modes - L+START switches between throttled/unthrottled/slomo mode.
Sleep - Activated from menu or 5/10/30 minutes of inactivity.

PogoShell:

To use as a Pogoshell plugin, first copy "pceadvance.gba" to the plugin folder then rename it to "pce.bin".
To make it work with US roms the name of the rom must not contain (J) or (j).
In the same manner Japanese roms should preferably contain (J) or (j), most Japanese roms seem to run on US hardware anyway though.

Multi player link play:

Go to the menu and change Controller: to read "Link2P"/"Link3P"/"Link4P", depending on how many Gameboys you will use.
Once this is done on all GBAs, leave the menu on all slaves first, then the master, the game will restart and you can begin playing.
If the link is lost (cable is pulled out, or a GBA is restarted), link must be re-initiated, this is done by a restart on the master and then selecting the appropriate link and leave the menu. *Note: Use an original Nintendo cable.

Advanced

SRAM:

The first 8kByte of the GBA sram is the pce sram, this can be exchanged between other pce emus, you may have to change MagicEngine's ini to old format.
Use a "CD-ROM System" rom to manage your pce sram's, press SELECT to access the SRAM manager, the US version is encrypted, don't forget to decrypt it.

CD Games in Pogoshell:

Make a PCEAdvance build with only a CD-ROM System rom, then copy the build to the plugins folder of Pogoshell.
Rename it to pce.bin, next edit the config, and add the following line to where the other plugins are in the config file.
- iso 1 pce.bin 2
Now you should be able to just add PC-Engine iso files to Pogo and run them.

Recommended games

Below are some games that runs well with PCEAdvance (a game compatibility list can be found in the gamelist.txt).

List of recommended games

1943 Kai (J)

Takes some time before it starts, but runs ok.

Aero Blasters (U)

Ok speed. (spr 6)

After Burner II (J)

Cool game.

Alien Crush (J)

Perfect?

Atomic Robokid Special (J)

Hani in the Sky (J)

Good speed.

Image Fight (J)

Kyuukyoku Tiger (J)

Mr. Heli

Screen to wide, otherwise ok.

Neutopia (U)

Seem ok, even save.

Operation Wolf (J)

Good speed.

Override (J)

Super speed if you turn off Timer IRQ.

Tenseiryu Saint Dragon (J)

Good speed.

These are just suggestions, please try what ever game you like (alot of US games doesn't work because they are encrypted, use PCEToy to decrypt these before you use them).

Also remember to click "US rom" in the builder if you want them to work).

Don't use overdumps as these are evil on PC Engine.

Make sure your flashing software allocates 8kByte/64kbit SRAM for PCEAdvance.

Using CD-ROM with PCEAdvance

To be able to use PC-Engine/TurboGrafx16 CD-ROM games you have to have a CD-ROM System rom in your build.

Use the normal builder to add any normal games that you want but also add a CD-ROM System rom to the compilation.

After that also add the datatracks from the CD and optionaly a .tcd file ("cue" file) to the compilation, this is easiest done from a command prompt or in a batch file.

Example: copy /b pcebuild.gba+cdgame.tcd+cdgame.iso pcecdbuild.gba

The .tcd files are not needed for all games, but the games that have several datatracks require it (not the ones that have a second copy of the first datatrack on the last datatrack).

You can only have 1 CD game in each build right now and you start it by choosing the CD-ROM System and then pushing start.

To use it from Pogoshell just make a build with only the CD-ROM System rom and use it as the plugin for iso files (and pce files).

Credits

Huge thanks to Loopy for the incredible PocketNES.

Big thanks to Hoe for the ROM-Builder.

Big thanks to www.XGFlash2.com for support.

Thanks to:

Zeograd for a lot of help with the debugging.
Charles MacDonald & David Shadoff for a lot of the info.

Some things to consider regarding emulation:

PCE has 64kByte of VRAM which can be background and/or sprites, GBA has 64kByte background and 32kByte sprite VRAM.
The PCE CPU runs at either 1.78MHz (like the NES) or at 7.2MHz (all games seem to use the fast mode), the GBA CPU runs at 16MHz).
