Runs faster, but it did Crash on me while using Qemm386.

With XMS running Doom -timedemo demo3 gave me 1091 gametics in 1853 realtics

And the Adlib Cards isn´t responding. Tried that music with Soundblaster and Adlib config. SFX works fine. No issues in other games afaik.

OMF 2097 works on the latest version (cache7)! Maybe random, but that's great :)

Make sure your qemm does not use the area from C000 to CFFF. It's rom and was readable before, but isn't anymore.

Yes, which area should be used now? :)

D000-DFFF should be fine.

There seem to be some programs using memory in the C800-CFFF area without possibity to turn it off, so i'm not sure how this will be handled finally.

under msdos, there are still sound problems:
Doom no music
Day of the tentacle, some sound effects are missing ...
Until the first cached version, there was no such problem

With Cache 6 & 7 Windows 98 locks up during boot. Windows 95 starts fine.
Volfied Locks up with Cache 6 & 7 on earlier builds Volfied would start if L2 cache was disabled.

I fired up the Windows 98 SE installer earlier today and it complains about the lack of an FPU. So this is likely not a bug, but rather missing functionality in the CPU.

I haven't tried installing Windows 9x on the core, but it might work if you run the installer with the /nm argument (bypasses CPU detection).

A list of install arguments can be found here: http://www.dewassoc.com/support/useful/setup_switch.htm

Edit: I should clarify the installer might work, not necessarily Windows 98 itself.

I have Windows 95 and 98 installed and running. I was just reporting since Cache6&7 Windows 98 locks up while booting into the OS.

Sorry for the confusion, I was replying to softtest9, who said the installer complained about the lack of an FPU.

I think you are correct about installing with a switch. I remember doing something like that when I first installed Win98.
I didn't have any luck installing Win98 SE.
@softtest9 I'm running Win98 4.10.1998

I am aware that there are ways to bypass the hardware check, but I figured it was put there for a reason and haven't messed with it much. I also have a preinstalled HDD image of Windows 98 SE which has always had trouble booting in ao486. I admit that I haven't tried earlier releases of Windows 98 though. Did Win98 4.10.1998 work in ao486 before the cache changes?

Windows 95 does work fine on my end too.

Yes, and it works with one of the earlier cache builds that has the L2 Cache on/off in the OSD, and as far as I can tell works fine with the L2 cache enabled. Win98 fails with the Cache 6 and 7 core builds.

Ah, that does sound like a bug/regression then.

It's maybe related to the more strict check for ROM access.
Before ROM could be written (which is kind of nonsense given the name), now those writes are ignored.

Maybe we need to do a testversion with OSD option for ROM access, so we can check if something is influenced by it.

The problem with these testversions is, that nobody really knows what they are build from.

Maybe BinaryBond can still tell which version is based on which GIT commit?
If not, please in future add the commit hash, so we can find out later when things break.

There is some strange behaviour regarding to Joysticks in X-Wing and Tie-Fighter. On the latest official release upon launching the game the calibration screen is coming up.

It still works this way in the first Test-Build with Cache, in all versions from Test2 onwards the calibration screen isn't coming up at all and manually triggering the ingame calibration shows the stick isn't detected at all.

This is not a general Joystick issue, as Doom or Wing Commander have no problems detecting the Joystick in the Test-Builds.

I thought it was just the first Duke Nukem, but it's Duke Nukem 3D! that game is not easy to move.

This may or may not help at all, but I know that on the Apple II, you can POKE or write to ROM addresses and they act as switches to turn things on and off. It doesn't change the ROM, but it does something when you write to it. I have no idea if that applies here.
