| Manually Obtaining the Address of a ROM Function

| Overcoming AMS Dependencies | Next

If a function is not in the jump table (at least in early versions of the AMS), there are often ways to obtain its address manually through some very dirty hacks. If possible, these hacks are really only used in those AMS releases where the jump table entry is missing, so the hacks are usually safe. The only exception is when the function is not listed in any jump table. If this is the case, the documentation will contain the type "Function (ROM Call)", but without an index.
If this is not the case, you can usually gain speed and decrease the program size by defining a suitable minimum AMS version.
