gbaemu4ds is a Game Boy Advance emulator for DS. The homebrew was entered into the GBAtemp Homebrew Bounty 2011 (DSi). == Installation == Download contains several versions: * gbaemu4ds alpha 2 fix4.zip - Latest version, with sound. * gbaemu4ds alpha 1 fix1.zip - Better compatibility. * GBAEmu DS r5 fix 4.zip - Last working DSi mode build. To install: * Unpack the zip file to the root of your SD. Delete the file patch.pat. * If you are using an acekard, keep the folder _rpg, else you can delete it. * Copy GBA homebrews and roms (.agb, .bin, .mb or .gba) to your flashcard (note that .gba is not supported for wood users (v1.45+)). See also the [https://wiki.gbatemp.net/wiki/Gbaemu4ds_Compatibility_List gbaemu4ds compatibility list.] == User guide == Run hbmenu.nds, browse to the ROM on gbaemu4DS, press A and choose "gbafile (start emu)" to launch it. Menu options: * gbafile (start emu) * savefile * bios * patch On the lower screen you will see some configuration options: * lcdswap - Press A to use the upper screen, B for the lower screen. * SaveType - You can use SaveTypeAutomatic for most case. * frameskip - Modify framerate. * autovsync - Press A to enable. And launch options: * oldirq * newirq * advirq * HblancDMA * forceHblanc * newirqsound * advirqsound * HblancDMAsound * forceHblancsound * newirqsoundsc * advirqsoundsc * HblancDMAsoundsc * forceHblancsoundsc * oldirqsc * newirqsc * advirqsc * HblancDMAsc * forceHblancsc === Launch options === gbaemu4DS lets you select the launch mode for your ROM. advirq is designed for commercial ROMs and has better compatibility with games. You can choose others for homebrew. However, there are exceptions like "Yggdra Union: We'll Never Fight Alone," which requires HblancDMA or forceHblanc (the latter works better than HblancDMA). [https://gbatemp.net/threads/gbaemu4ds-gba-emulator-for-ds-i-dsi-entry.281715/post-4520245 Notes on other options.] === Saving and loading === To save a game, press Y or Up+A+B, then select "save". To load a save, select load the save instead of the ROM, then click "savefile" and pick the ROM to boot it. Since Version r41, there's also an auto detect function for save files. === Troubleshooting === The compatibility isn't perfect right now. If a game crashes, you could try a different version or save type (128k Flash usually fixes most white screens). Also, (E) ROMs tend to work better. Here are some things to try if a homebrew or ROM crashes: * Hold the X button at the point it normally crashes. * Switch to another mode like oldirq, newirq, advirq, HblancDMA, or forceHblanc. There's no GBA border implemented, and you might see a glitchy fuzz around the sides of the screen. You can try using sc versions, which scales the ROM to fit the whole DS/DSi/3DS screen. == Controls == Up+A+B - Menu == Screenshots == https://dlhb.gamebrew.org/dshomebrew/gbaemu4ds2.png https://dlhb.gamebrew.org/dshomebrew/gbaemu4ds3.png == Media == '''gbaemu4ds settings explanation''' ([https://www.youtube.com/watch?v=fxUc7KHZKi4 ichichfly]) <youtube>fxUc7KHZKi4</youtube> '''gbaemu4ds alpha 1 first com rom sound test''' ([https://www.youtube.com/watch?v=dFw7L0N87Ac ichichfly]) <youtube>dFw7L0N87Ac</youtube> '''Play GameBoy Advance Games On Any R4 Card!
