Another result with EmuTOS 1.2 on my real Atari 1040 STE (4Mb) :
ST-RAM 403572 b (~394 KiB)
TT-RAM 0 b (~0 KiB)

Weird. So TOS is reporting no free RAM left (or only 400k in the second case), right at the beginning of the game, before all the large allocations are made. The first allocation then fails. Do you have any desktop accessories, drivers or RAM-disks installed which could explain this? I'm pretty sure a vanilla Hatari 4MB STE would work.
