You seem to be changing the TLP, but there is nothing I can do about the TLP.
TLP has no free space because games are made using a lot of data.
Also, TLP uses a lot of complex ASM extensions, so FEBuilderGBA's rebuild can not be used.
Originally, you can compress capacity with rebuild, but the original extension used by TLP is too complicated and can not be analyzed.
Therefore, you can not use rebuild.
Unfortunately, this can not be helped.
There is no way other than managing the address yourself.
