Welcome back LexiTV!
If you don’t mind PMEs, I can recommend you what I created myself together with FEU:
|| Fire Emblem 6 - Lyn’s Bizarre Adventure ||
And it’s prequel:
|| Fire Emblem 7 - The Blazing Silver ||
Both of them I’ve made separate patches that has Fixed Growths mode enabled.
All available on the main download links.
There’s one more thing from FE7’s! An expansion created by TritraSerpifeu:
|| Fire Emblem 7 - Elysium Ablaze ||
This is basically a version with everything fully modified and expanded, from maps to story, instead of being a classic PME. However I believe it doesn’t actually have a separate Fixed Growths patch yet, but if you really find it interesting you can call it’s creator, TritraSerpifeu, so that a patch can be easily and readily available.
(Update: TritraSerpifeu released the separate patch with Fixed Growths!)
That’s everything from what I ‘know right away’ and is available right away, because yeah I’m actually in the same boat; I remember a lot of really good og hacks but my mind is going blank on which ones has fixed growths available on top.
Hope these are all right, and wish you luck on finding the ones you mentioned.
