RE3 is a WIP port of the re3 project to Nintendo 3DS. Only New 3DS is supported. ==Installation== There are four seperate 3DSX files (re3.3dsx, re3-stereo.3dsx, re3-txd.3dsx, re3-stereo-txd.3dsx) and bonus files (miami.3ds, miami-stereo.3dsx). * The re3-*-txd builds do texture compression on your 3DS and generate a TXD.IMG/TXD.DIR. * The vanilla builds re3.3dsx, re3-stereo.3dsx assume you have converted the game files to a native format using txdcnv (provided). * The miami.3ds files haven't really been tested in a while and they only do texture conversion on the 3DS. ===Prerequisites=== You will need the PC version of GTA III (other versions might work) and convert the texture to run on the 3DS. ===Texture conversion=== You need to use txdcnv to convert the game files to native formats. Create a directory for the output files. The txdcnv build is only for Linux x86-64, you will have to use re3-txd.3dsx or compile from source otherwise. ./txdcnv [gta3 root] [output root]. The [output root] will be like this. * .: ** models txd * ./models: ** fonts.txd generic.txd gta3.img menu.txd particle.txd ** frontend.txd gta3.DIR hud.txd MISC.TXD * ./txd: ** LOADSC0.TXD LOADSC15.TXD LOADSC20.TXD LOADSC2.TXD LOADSC8.TXD SPLASH2.TXD ** LOADSC10.TXD LOADSC16.TXD LOADSC21.TXD LOADSC3.TXD LOADSC9.TXD SPLASH3.TXD ** LOADSC11.TXD LOADSC17.TXD LOADSC22.TXD LOADSC4.TXD mainsc1.txd ** LOADSC12.TXD LOADSC18.TXD LOADSC23.TXD LOADSC5.TXD mainsc2.txd ** LOADSC13.TXD LOADSC19.TXD LOADSC24.TXD LOADSC6.TXD NEWS.TXD ** LOADSC14.TXD LOADSC1.TXD LOADSC25.TXD LOADSC7.TXD SPLASH1.TXD Mipmaps are actually 100% necessary. They drastically improve performance and memory management. Older versions did this on the 3DS but it took too long. ===Updating game directory=== You will overwrite the files in [Game root] with these modified files. Copy the files from [Output root] to [Game root]. From (this archive) src/gamefiles copy "data" and "TEXT" to the [Output root]. This will overwrite PARTICLE.CFG and various GXT files. ===3DS File system=== The game files are stored in a hard-coded directory on your 3ds. Create the directory sdmc:/3ds/re3/ (or sdmc:/3ds/miami/ for VC). You can copy the contents of [Game root] to /3ds/re3/, but if your a bit more OCD you only need the following directories: * sdmc:/3ds/re3/anim * sdmc:/3ds/re3/audio * sdmc:/3ds/re3/data * sdmc:/3ds/re3/models * sdmc:/3ds/re3/mp3 * sdmc:/3ds/re3/skins * sdmc:/3ds/re3/txd ===Music files=== Copy .wav|.mp3 to sdmc:/3ds/re3/mp3/ (.ogg isn't supported). ===Installing=== Copy re3.3dsx and re3-stereo.3dsx to sdmc:/3ds/ (or anywhere really). Launch with Homebrew launcher. ===Building=== To build from source, you only need devkitpro/devkitARM. The Makefile has only been tested on linux (devuan beowulf), but it should work on mingw/msys or cygwin. Developer has included all the libraries needed. Make sure you environment has DEVKITPRO/DEVKITARM. $ . /etc/profile.d/devkit-env.sh $ cd re3/build $ make or for stereo set STEREO in your env. $ STEREO=1 make make upload sends to hb-menu. make debug call gdb and connects to 10.0.0.2. ===Additional notes=== Most the new contents are yet to be updated in GitHub. A good starting point for customization is in src/core/config.h. If you want to enable online texture compression enable TXD_USE_CDIMAGE. There are two versions of librw in vendor for mono and stereo rendering respectively. 3DS platform specific code is at src/skel/3ds. You may consider build from source as the binaries are not tested due to the lack of time. ==Controls== '''Main menu:''' L+R+Up - Access Free-Roam script L+R+Down - Access Debug script '''In game:''' L+R+Down - Access Debug menu ==Media== '''Grand Theft Auto 3 ported to the Nintendo 3DS Install+Gameplay 11.14 CFW''' ([https://www.youtube.com/watch?v=4QeESx6SqL4 BandiPower]) <br> <youtube>4QeESx6SqL4</youtube> '''Grand Theft Auto 3 (re3) Nintendo 3DS Gameplay''' ([https://www.youtube.com/watch?v=NyOHuoo7BsA Stranno]) <br> <youtube>NyOHuoo7BsA</youtube> '''re3 on 3ds''' ([https://www.youtube.com/watch?v=60H8mYGHroM Gogeta007yBro]) <br> <youtube>60H8mYGHroM</youtube> ==Known issues== * Menus and loading screens are blurry. * Fonts are not displayed properly due to mip-map generation. This is a recent regression from implementing txdcnv. * Material FX environment mapping isn't accurate. * Cars are very shiny. Shinier than the mobile port. * Dynamic lighting (directional lights) is broken. May have something to do with floating point accuracy. * Skinned geometry is jagged/glitchy, suspect it has to do with floating point accuracy. * There is a black roads glitch, presume that has to do with blending. * MP3 playback slows things down (the audio thread runs on the primary app-core). * Pager/text messaging is unreadable. * Bottom screen is not in use yet (only play-tested the first third of the game by the developer). ==External links== * GBAtemp - https://gbatemp.net/threads/wip-re3-3ds-port.586374
