[Issue]: Kirby Tilt 'n' Tumble (GBC) does not save any savedata

[saulfabregwiivc]

Describe the bug

On VBAGX, the game Kirby Tilt 'n' Tumble doesn't save any save data. It says "Saving..." when saves data but when i reset or next time i load the game, the File Select screen just shows there's nothing saved (all savefiles says EMPTY / NO DATA).

But oddly on VBA-M 2.1.4 the game saves the savedata fine, and the savedata shows on "File Select".

To Reproduce

1. Load the game ROM (unpatched, the original one.)
2. Enable "Match Wii Controls".
3. Play for a while until you see a "Saving..." screen, then let it save.
4. Reset the game, and choose "GAME START". The file select shows there's no saved data.

Expected behavior

I expected VBA-GX to save the game data of Kirby Tilt 'n' Tumble (the saved data appears on "File Select" screen.

Pinging you cause i think you know more of the code handling in VBA-GX.

Recently, a collaborator of VBA-M made this fix for fix saving in Kirby Tilt 'n' Tumble, but since this was made in updated upstream VBA-M and this emu is based on an old version of VBA-M, can you help me backporting this fix to VBA-GX?
