custom weapons

I personally think its my version of yychr

Why don't you download version 0.99? The tile to draw on the right are more accurate than version 0.98. Some other stuff has been improved too. There was an updated version in april, but I haven't seen anything different from the previous 0.99 that has been out for some time now

As for the compressed graphics, it's exactly as stated in zeemis tutoria:

1) Offset to enter are from 12E200 (start) to 12ED43 (end) in PerrSpriteViewer (headered ROM).
2) Copy to buffer
3) Compress ----> address 12E200 ---> choose file (create one) ---> Decompress.
4) Open the file in YY-CHR (4BPP)
5) Do custom shield
6) ReCompress
7) Save ROM
8) Voilà!!
