How do you get Jazz Jackrabbit running with JEMMEX? I always get: Copy code to clipboard 1 Loader error (0025): cannot initialize It's been said on this thread that the game works with VSBHDA, but I can't get it to work. Other protected mode games like Doom, etc work fine, with sound and all.

This problem almost certainly can be solved - the simplest approach probably by not using the sound hardware's IRQ at all, and instead using another timer device. I'm also interested in your APIC configuration. Could you run the APICinfo tool found at https://github.com/Baron-von-Riedesel/APICtools …

So, is it true that USB3 is a problem for DOS compatibility? My understanding is that, if PS/2 emulation in the BIOS is correct, USB should work correctly even if it's USB3. The computer has two COM ports, but I don't think there are serial keyboards or USB-to-serial adapters to use USB keyboards on …

Hello there, I found an apparently nice modern computer for DOS usage: https://es.aliexpress.com/item/1005003330185279.html It uses a compatible GPU (Gen7 is supposedly still good for DOS, isn't it??), CPU has no L3 cache, and SBEMU works on it nicely so I even have SoundBlaster audio on it. However …

So far the only other game I've tried was Monkey Island 1. No issue with T4 with MI1, but I'm aiming to taking some time to do a deeper dive with other games. Could you please try Elder Scrolls: Arena? On MS-DOS 6.22, I can't get the game to launch. On FreeDOS, it locks after character creation.

Just wondering, if there a curated ISO with DOS and games and utilities etc... that can be downloaded and runs on the TL2? Sorry if this is an irrelevant questions.

Have you guys been able to get SuperFrog working with this? Gives me a nice "Can't build video selector" error message once SBEmu is loaded. Works (silent) without it.

Thing is, Tyrian is supposed to run right on a Pentium machine. So why does it display the …
