THIS is the function you call from the MegaDrive or whatever.
This figures out whether it's a genie or hex code, depunctuates it, and calls the proper decoder.
[in] | code | Game Genie or hex code. |
[out] | result | The resulting address:data pair is returned in the struct patch pointed to by result. If an error results, both the address and data will be set to -1. |
void genie_decode | ( | const char * | code, |
struct patch * | result | ||
) |
Decode a Game Genie Code.
This function converts a Game Genie code to an address:data pair. The code is given as an 8-character string, like "BJX0SA1C". It need not be null terminated, since only the first 8 characters are taken. It is assumed that the code is already made of valid characters, i.e. there are no Q's, U's, or symbols. If such a character is encountered, the function will return with a warning on stderr.
The resulting address:data pair is returned in the struct patch pointed to by result. If an error results, both the address and data will be set to -1.
[in] | code | 8 character Game Genie code. |
[out] | result | The resulting address:data pair is returned in the struct patch pointed to by result. If an error results, both the address and data will be set to -1. |
void hex_decode | ( | const char * | code, |
struct patch * | result | ||
) |
"Decode" an address/data pair into a structure.
This is for "012345:ABCD" type codes. You're more likely to find Genie codes circulating around, but there's a chance you could come on to one of these. Which is nice, since they're MUCH easier to implement ;) Once again, the input should be depunctuated already.

[out] | result | The resulting address:data pair is returned in the struct patch pointed to by result. If an error results, both the address and data will be set to -1. |
