Great update I can now add my fakemon and gen 8 thank for you updating this lovely base :)
 
pge isn't working for me dose anyone else have this problem

The base rom must be within the same folder where the .ini and both must have the same name.
The version of PGE that I made available has a .ini compatible with the base rom, .ini is called test.ini.
Just rename the base rom to test.gba and leave it in the same folder as the test.ini. Then open the base rom on the PGE.
I just took the test here and for me it worked without problems. Test and tell me if it worked or not.

So I found out the hard way that you have to start over it's sad :(
 
I found a bug: when you use M-Lunarizer/Solarizer and DNA Splicer, the game freezes.

Thanks for reporting this bug. Below I'll leave a new little update with a fix on this.
-----------------------------------------------------------------------------------------------------------------------------
Small Update v1.4 07-10-2021:
Fix: HM's found in routes and/or obtained from Npcs.
Fixed all the items that froze the game when using it.
Bug Fix Box HP in Double Battle.(Bug Fix also applied to Modexe data. Reapply the HP White Box or HP Black Box to fix this bug.)
New: ModExe exclusive to the base. For now I plan to add only graphic content to it.
What has available in modexe so far:
Box HP Black
Box HP White
Party Screen Base
Party Screen BW
Party Screen HGSS
Slightly altered bag(No re-coloring for now.)
New graphics mods will be available in the future, stay tuned.

Patch and ModExe for download in the attached file in the main post.

good update, and when you said that my update problem isn't gonna happen again, how to update the edited rom base that i had?
anyway why theres no power-up punch move?

You can use the CTRL + K command in HxD to compare the data between the different versions, so you can know what has changed. It's a laborious job, but I can't think of other methods to make updates available, unless via patch. But I believe that from now on the next updates will be only bug fixes, that is, simple changes to the base code. As for Move Power-Up, on the base it has the name Grow Punch.
 
i try open new mod exe but it says can not find hack.ini but itts in the folder

Follow this path: With Modexe open, go to the "File" menu and select the "Load ini" option, then navigate to
the folder where the are hacks.ini, and select it. Then just open the rom in Modexe.
 
Small Update v1.5 09-10-2021:
Fixed all TM's found on routes or obtained by NPC's.
TM49 Snatch on S.S Tidal is now TM49 Leech Fang.
Fixed TM's for sale on Mauville Game Corner and Lilycove Department Store.

Patch the updated rom in the attached file in the main post. From now on I will make the
update available via Modexe, I believe this will be more practical for everyone, so you will not
need to modify your rom hack with each new update. With Modexe you'll be able to apply the
update in just two clicks, easily, quickly and efficiently.
