Thanks I'll try this.@Jabe you can try to install the latest d2x beta v9 into IOS slots 249 and 250 or try a base different from 58 (like 38 for instance) for ios249
get the wads using latest ModMii download page 4.
your older loader is running with ios222 base 38 v5.1 (Hermes) unsupported by new CFG loader
What are:
?222[38]v4
223[38+37]v4
Is it cIOS Hermes v4 ?
