I need help with inserting new OW sprites. I followed part three of Darthatron's guide
here, and did the process of adding new OWs (just one extra OW as a test), but when I start up my test rom, everything is fine until the end of the Nidoran/Gengar intro or I skip to the title screen, but then I get a black screen and nothing else.
What I did was:
1. Copied the original OW table from the location "0x0039FDB0" (604 bytes)
2. Used FSF to find an offset of free space containing 608 bytes.
3. Went to (or "goto" in the hex editor) said offset and pasted the original OW table (604 bytes) over the first 604 bytes of 608 bytes of free space. Replaced the last 4 bytes with the pointer to the new OW sprite data.
4. Used FSF to find 36 bytes of free space, enough to add sprite data for the new OW.
5. Went to said offset and replaced the 36 bytes of free space with the sprite data for the first hero OW sprite.
6. Went to the pointer for the original OW table and and changed it to the pointer for the new 608 bytes of OW pointers.
