The Wii U file system uses the Title ID to organize the games in different folders. When you install a game that has the same Title ID of another that you previously installed, the contents of the folder corresponding to that Title ID are overwritten with the files of the new game. In other words, to avoid a problem with your CBHC installation you should take care that the Title ID of any game does not match the Title ID of the game you used for CBHC.
As far as I know my program does not generate conflicts with Title IDs of official games.
My injector generates the Title IDs as follows:
For Famicom/NES: 0005000061XXXXZZ
For Super Famicom/SNES: 0005000062XXXXZZ
For N64: 0005000064YYYYNN
For GBA: 000500006AXXXXZZ
For NDS: 00050000D5XXXXZZ
Where XXXX is the CRC16 of the ROM, ZZ is an index that corresponds to the Virtual Console version, YYYY is the CRC16 of the N64 ROM concatenated (byte level) with the configuration file ".ini" and NN It is a value consisting of three bits of flags (Darkfilter, Widescreen and "Frame scale-traslation") plus five bits of a corresponding index the version of the N64 Virtual Console.
Base games with the same version of the Virtual Console will provide the same ZZ index or the same NN value (if the flag bits are also the same).
If you are curious you can check the indexes of each version of the Virtual Console in the file "PhacoxsInjector_VC_Hash_List.xlsx", mentioned above.
