CTGP-7 - Custom Track Grand Prix 7

CTGP-7 is a modpack for MK7 which includes several Custom Tracks, texture hacks, music hacks... (and Red Yoshi :3). It can be played using two different methods: HANS or NTR CFW. Here are the advantages of each one:

- NTR CFW (recommended): Easy install, can enable/disable custom tracks, can update itself without a PC, can go online if you have a prepatched 1.1 copy and you are in lastest firmware. NTR is not a standalone CFW, it works at the same time as your installed CFW, so it only makes a few patches to allow plugins to be loaded to games. In this case, it will install OnionFS that will redirect romfs reads to the SD. Works on versions from 9.0.0 to 11.5 CFW
- HANS: Launches from Homebrew Launcher, so no need to install anything else, however, it can't update, nor can disable/enable custom tracks. You can go online if you are in lastest version, or you use this. Works on versions from 9.0.0 to 11.3 (Doesn't work with 11.0 browserhax) (11.4/11.5 unknown)

Q. Which method do you recommend?
A. I recommend using NTR CFW, as it can be installed very quickly, updated without the need of a PC and allows some extra features. If you don't have CFW, then use HANS method, since it can be used with Homebrew Launcher.

Q. I can't go online because the game tells me to update Mario Kart 7. (HANS method)
There are two different MK7 versions, 1.0 and 1.1. You can only go online if your game is in 1.1, even without the eshop 1.1 update patch. Let me explain this, Back when Nintendo released the 1.1 patch in the eshop (about 2012), they stopped producing 1.0 cartridges, and started producing 1.1 cartridges, which had the update patch already applied in the rom itself. I'll refer to those games as prepatched games. (this applies to cartridges and digital versions). Only 1.1 prepatched games will be able to go online, because HANS just doesn't load the eshop update patch. (You may still see the v1.1 label in the multiplayer menu, but that's just because the romhack is based on 1.1 files). If you have bought a 1.0 digital version, backup your save, uninstall the game and download it again from the eshop. This action will install the prepatched 1.1 game. If you have a 1.0 cartridge version, nothing can be done right now.

Q. The game crashes at some points.
A. This mod is not perfect, and that's why it's still in BETA. If the game crashes during a race, try disabling L2 cache and cpu settings in luma if you are using CFW. Else, please report it here, or if you don't have a github account, send me a PM.

Q. Will this mod overwrite my MK7 game?
A. Nope, the patches are temporal and will be gone after a reboot. It will however overwrite ghosts if you beat your previous ones in Time Trials. You can backup your save with JKSV.

HANS method (not recommended):

In this guide I assume:
- You have access to homebrew launcher, and have the latest starter kit copied to your SD.
- You have a MK7 copy (physical, digital or installed cia)
- You can open zip files.
- You know that MK7 means Mario Kart 7 :P

0. If you already have a decrypted cia/3ds file the same region and version of your game, or dumped from it, go to step 6.
1. Download braindump, and copy the braindump folder to the 3ds folder in your SD.
2. Get into homebrew launcher and select braindump and press A. It will ask you for a target title, select MK7 and press A.
3. It will start dumping your game, if it fails, power off and try again (may need a few tries).
4. After it has finished dumping, extract your SD and go to your PC. You should see "0000000000030X00.cxi" (X = 6 -> JAP, 7 -> EUR, 8 -> USA) on your SD root.
5. Download official CTGP-7.zip from the link above, and extract it somewhere in your PC. Then copy "0000000000030X00.cxi" to the same folder you extracted CTGP-7.zip
6. Run Build_CTGP7.bat (it may tell you not to execute bat files if you don't trust the source, it's up to you if you trust me or not :P).
7. A black window will open, ask the questions by pressing a number and then enter. (Game region, cia install availability and the method you want to use.)
8. After you have selected hans method in the black window, it will ask you to for your MK7 cia/3ds/cxi filename. Just press 00 and then tab key, so it autocompletes to 0000000000030X00.cxi and press enter.
9. Now it will start building CTGP-7, just wait until it finishes.
10. Go to log folder and open errorlog.txt, if you see any errors, read the troubleshooting section before proceeding.
11. Copy the contents of "output" folder near Build_CTGP7.bat to the root of your SD.
12. Insert the SD in your 3DS, go to the homebrew launcher , you will see CTGP-7 icon, run it.
13. Enjoy.


NTR method (recommended):

In this guide I assume:
- You have a MK7 copy (physical, digital or installed cia)
- You know that MK7 means Mario Kart 7 :P
- You have a CFW set up. (I recommend Luma3DS)
- You can install cias. (I recommend using FBI)

1. Copy the CTGP-7.zip file (use Google to find the CTGP-7 download) to the SD root (the zip should be 200MB more or less). Don't extract it, just place it there.
2. Install the CTGP-7 installer cia (qr code for FBI -> Remote Install -> QR Code):

3. Launch the CTGP-7 installer cia, it will do the rest of the process automatically. (If you get error codes, read the troubleshooting section.)
4. Once it's done, the installer will automatically be replaced by the CTGP-7 manager cia, don't remove it or install the CTGP-7 installer again!
4.1: You may get an error the first time you try to launch CTGP-7, a reboot will fix it.



- Black screen after selecting CTGP-7: You may have an old starter kit or *hax installed, try updating to lastest starter kit and lastest *hax version. (Tested with *hax 2.8). NOTE: Rosalina homebrew laucher is not compatible with HANS, use NTR method instead.

- Missing target title:
It can't detect your MK7 copy, either the game card isn't inserted, or you have selected the wrong region in Build_CTGP7. (Remember that "0000000000030X00.cxi" X = 6 -> JAP, 7 -> EUR, 8 -> USA).

- CTGP-7 icon doesn't show: You haven't copied the files to your SD correctly, make sure you copy the contents inside "output" folder, not the "output" folder itself to the SD card root. Also make sure you are using the most recent homebrew launcher.

- The main menu shows version 1.1 but I can't go online: The 1.1 string is there because the mod is based on 1.1 files, however if you have a 1.0 game, you won't be able to go online. Read the FAQ for more info.

- There is an error inside errorlog.txt:

- Error: "Not decrypted/MK7 game/error extracting romfs"
- Solution: The cxi is corrupted (try dumping it again, braindump may create bad dumps sometimes), or it isn't Mario Kart 7.

- Error: "Error opening input file"
- Solution: This can be because you have entered the wrong cxi filename, or braindump didn't dump the cxi correctly. Repeat from step 2 if this is the case.

- Error: "Error creating (foldername)"
- Solution: Ignore it.

- Installation error codes:
You may get error codes if something goes wrong in the installation, here are their meaning:

- Errors 1 to 5: The zip data is corrupted and some files are missing, check you have dowloaded the latest zip and installer.
- Error 6: The "CTGP-7_installer.cia" and "CTGP-7.zip" versions do not match, make sure you have downloaded lastest CTGP-7 zip and CTGP-7 installer.

- After launching CTGP-7, an error pops up: This may happens sometimes. Just save and reboot and try again. :P

- #Unknown firmware: Make sure your system version is compatible with NTR method. If Nintendo has released an update recently, a CTGP-7 update will be released soon to fix the problem. It may also happen because your CFW is outdated.

- Infinite 3DS logo when launching MK7 or starts unmodded: Make sure your CFW is updated. Make sure you are not using an outdated CFW such as rxtools. Make sure you are not using an outdated CTGP-7 version.

Platinatic That's pretty cool!
The fact that it can be done using Tube/ironhax is even better!
Good Job!

MK7tester In case anyone doesn't know yet, CTGP 7 v0.3 has been released.

- Added NTR CFW support.
- Added 4 new tracks (SNES Ghost Valley 2 by Stewie, GCN Peach Beach, SNES Choco Island 2, and GCN Waluigi Stadium by me)
- Added some custom kart/emblem
- Added Gold Mario and MR L.
- Removed Sandcastle Park

According to pablo, this update is going to be followed by some smaller updates adding more tracks.

Also, if pablo reads this, one of these next updates should REMOVE GCN Waluigi Stadium. Although I can't test it myself, a few sources have told me that the track lags really bad online despite working fine on single player. So, unless Pablo's okay with it under-performing online, we could have Stewie's Miku Pinball texture or Alex's cool cool pinball texture hack until there is a release for Waluigi stadium that is more stable online. It saddens me to want to exclude my own port, but it will be aggravating if someone chooses random in a CTGP room and it gets Waluigi stadium, only to prompt a long, slow, boring laggy race.
