Time to replay it on SNES (years ago I experienced it on GBA) and get some rips done.
Used emulator is bsnes-rawpalettes, a true colour mod for bsnes+ and my tool of choice.
Used ROM is the U [!] version to make sure the codes below work properly.

Misc.
NPCs
Enemies & Bosses
Animals
Battle Backgrounds
Some Maps

No Random Battle by Helder / slab
022F-C748 or 7E1090:00
The first one makes use of an item effect which will give out a message prompt when it runs out. It always renews itself as long as the code stays activated, but also gives out the prompt.
2nd one is labelled wrong on gamehacking, it raises the encounter rate enormously.

Walk through Walls by Helder / slab
6DB4-C72E or 7E1002:02
First one works fine everywhere, therefore haven't tried the second one.

Invincible in Battle by Helder / Unknown
60AE-C46A or 7E104E:4D
First one doesn't work, you still die. The second one has your HP decreased to a minimum but keeps you alive.

Almost infinite Money by Helder
DEE1-C7F3
Shows money in menu, but I can't buy above my actual GP. I need to get a different one.

Infinite Magic in Battle by Helder
C9C3-CF63
Haven't tried it yet.

Walk faster by Breath of Fire Editor on Romhacking
DDB3-372E
DD8F-4DBA
Have it activated all the time.

Various sprites, the game is easy to rip. This is everything up to the Knight boss in Nanai dungeon.
This boss is just too strong, even with the best sword and Lv. 8 I cannot beat him (or I just need more herbs).

Defeated the wizard and got most of everything until that point.

Now in the jail cell with Karn.

The Gremlin was really tough to beat, didn't remember that I struggled so much with him.

Balancing is also a bit weird (either this or because I was skipping a lot with NoRandomBattle):

- Camlot Castle is really good for levels, but after you beat the Frog only the low-level enemies on the world map remain.
- Therefore the Knight in Nanai was way too hard, damage output from Ryu was very low (even with LongSD) but the boss hit very hard.
- Wizard was easy for Ryu and the overall enemies in that area were managable.
- It continues until you get to the Forest of Despair, which throws easy-to-beat enemies with high EXP & GP at you. Bosses are easy too.
- Wisp on the flying island was only kinda hard, since Bo and Nina were falling way too fast but Ryu was just tanking everything. Fought with him alone and won easily. Enemies were low level from previous areas.
- Stone Robot: Regular enemies, boss was managable. Then... the Gremlin appeared after the wedding. It felt like he had a whole second energy bar after I cleared the first one. Luckily I had all these items for attacking and healing, Bo couldn't even last two hits.
