The first version of my small hack is complete. I made it for myself mainly but if anyone wants it here you go:
https://files.catbox.moe/8s9p9f.gbcIf anyone is interested in using the code for their own hack or editing the teams/dialogue/etc. I can upload the source code to GitHub.
Features:
>Gym rematches for every Gym Leader with progressing teams (see image for schedules/requirements)>Silver now gets stronger after each rematch at the Indigo Plateau>Elite Four has two rematches, getting stronger each time>Renewable type-boosting items (use Thief on type specialists in their final rematch)>Linking Cord item for trade evolutions in Mahogony Town mart after clearing Team Rocket HQ>Trade + hold item evos are now just use item evos>Pokégear contact list expanded to 30 in preparation for Kanto Pokégear rematchesEverything else is unchanged to keep the experience as close to vanilla as possible.
Also, I think I forgot to make it so Silver doesn't increase his levels if you lose to him, so I'll fix that in the next version, as well as some team changes maybe.
