If I enable 128Mb of Z3 RAM on 0.8.26 (latest version as of 19-05-2004) the emulation crashes on boot. This is a reproducable error that does not happen with 64Mb or less of RAM.
Any ideas? I'm on WinXP, SP1a DX8.1 - though I'm not using the DX filter for old screen resolutions compatability, 512Mb RAM.
