ST/AMIGA Same game, different sprites?

[SToS]

Not sure where to post this, so graphics seems most appropriate...

An Observation:

Whilst disassembling and ripping sprites etc, I noticed that the game Spikey in Transylvania has different sprites for Spikey's death, Spikey seems to be in a onesie on the ST and the wine bottle on the Amiga is bigger!

Both use 4 bitplanes and a mask with 16 colours, so why? I don't see a technical reason for this.

It looks like the Atari ST version was a port from the Amiga due to HUNK id's and "graphics.library" strings in the code.

Addendum:
If you type "BOTTY GRAPES" at the intro screen, your lives will not decrease!
Or "I AM A GIT" on the Amiga.

Interesting to see, thanks for the rip

Spikey is not wearing a onesies... he is naked

If the Amiga version runs with only 512 KB, it may be a size problem in RAM. No sound generator on Amiga: samples have to be played by a DAC, so it's more RAM consuming than the Atari's PSG.

Same problem with Dungeon Master. Amiga version needed 1 MB RAM to place the digitalized sounds, versus Atari with only 512 KB RAM could run nearly the same game.

I'd never paid this game much attention other than being half aware it was a play on the Dizzy engine. Reckon they just totally failed to secure the license for Hagar the Horrible? First time i've seen the sprites!
