You mean that the leaked source is from the unreleased English version of the shindou revision, and you can create an English shindou by compiling it? If so, we can maybe expect a no-intro release of the compiled rom. Certain prototypes like Bound High for Virtual Boy only exists as a compilation of its leaked source code, and it's included in the no-intro set.
Well, the issue is that compiling isn't particularly uniform; it was made for the iQue SDK in mind, and the iQue SDK contains a N64 library that breaks rumble/saving/other functions on N64 hardware
This means that to target N64 you have to build the whole SDK from source code
Also, the "English Shindou" is really just the JP shindou with english text, the rumble texture is still japanese and the mario sound changes are still there
If it is allowed, i can post a .bps patch you can apply to JP shindou so you don't have to do all that work
