Same problem as https://github.com/libretro/reicast-emulator/pull/24
in unix that iteration would not work if the path of the original .gdi file (where we are finding the 'parent directory') was:
1. not existent, ie a gdi on the same directory as the current. It was iterating until the index 3 and stop there. Disaster strikes later ofc, if the first characters weren't C:\ or other thing like that.
2. in a relative subdirectory that is 'small enough' ie: a/crazy-taxi.gdi. In this case the last '/' wouldn't be found, the derived string would be 'crazy-taxi.gdi' and the file not found ofc.
Anyway, this can be solved simply by searching the whole string and using a signed integer. It will go up to -1, stop iteration and increase to 0 on the len++.
Dunno if using relative subdirectories for the tracks on *other* platforms works because of the path separator being different from what's inside the gdi but with this code fixed it works on linux with / at least.
- Fix coreio fsize
- Fix coreio fopen to seek to 0
- Fix coreio/http to smart-escape urls
- For urls that include \ or % in the filenames, you have to pass them
escaped
- Update gdi parser to use (mostly) streamstream. That code is horrible
and should be rewritten
- coreio core is hacky and horrible at places as well
- Update imgreader to use coreio
- Update cdi parser + driver to use coreio
