Unity (or mono in that case) is a bit special when it comes to handling file I/O, as before any operation (read, write) it will do a call to `GetFileType` to determine how to set the parameters for the following winapi calls. Handles that we replace with `iohook_open_nul_fd` however don't return the expected `FILE_TYPE_DISK`, as a null handle is a `FILE_TYPE_CHAR` which works by chance for serial ports, but not for files: Related: https://gitea.tendokyu.moe/TeamTofuShop/segatools/issues/116 Reviewed-on: https://gitea.tendokyu.moe/TeamTofuShop/capnhook/pulls/7 Co-authored-by: kyoubate-haruka <46010460+kyoubate-haruka@users.noreply.github.com> Co-committed-by: kyoubate-haruka <46010460+kyoubate-haruka@users.noreply.github.com>
