Might be worth looking into the "squashfs" idea for compression;

Maybe its using the "fast filesystem" by default, I'm sure there was an option when formatting on the A1200 (its over 25 years ago, I could be wrong).

How did you manage to fry the HDMI? By plugging it into a monitor! It must've been static discharge or something. I had a splitter & several cables connected (but the switch on that *should* have disconnected their connection) so I've no idea what caused the fault, I suspect the monitor itself. There initially seemed to be a bad connection, I ...

Anyone have any radical or potentially dangerous stuff they'd like me to test for them? I fried the HDMI port on my DE10 Nano & now have a replacement. I'm happy to run some tests on the old board that might cause it grief. It still works fine using VGA output add-on board (which I'd prefer remains unharmed). Otherwise I may donate it or do som...

Thanks. I have a set of speakers for the MiSTer anyway as it's connected to a VGA monitor. I'm hoping it'll be better quality than an old TV.

I've got 2 CPC 464 monitors in the attic & was thinking they'd probably be pretty good displays for the MiSTer. I see plenty of guides on connecting an Amstrad to a TV's scart, RGB or even VGA monitors. I see nothing about using a CPC monitor with RGB/VGA out though. I haven't researched this thoroughly, I just wondered if anyone has tried it, ...

Thanks, I'll have to test it sometime.

For CD I use "Magicdisc". It's free, no idea if it works with audio CD, can't see why not.

Maybe the person who wrote the benchmarking software included a "bullshitting" routine. I recall reading of an Amiga virus that made the floppy drive run 8x faster (with the side effect that it wrecked the drive in a fairly short time). I tried for years to catch that mythical virus. If it can be done for the floppy maybe the HDD is possi...

I have always kept having some issues installing Win98SE. I have one where I set it up with PCem on my PC emulating a PC similar to AO486, but it has audio problems. I have won that I managed to install fully on the AO486, but it is unable to install Daemon Tools. The installation itself went without problems though. I think if I take that Win98SE...

When I ran fdisk on the latest release it seemed to support LBA. I was hoping that'd allow bigger VHD/HDD sizes.

Ooohhhh most definitely yes.

I just read running a math coprocessor emulator can speed up Doom. Personally I'm not interested in it, but was looking up the emulator for something else & thought I'd pass the info on in case anyone wants to try it.

You can download several 8087 emulators for DOS here:

VF1/2,HotD, OR VR?

See that "Pentium" sticker on top of the image you just posted?

You have your answer

They may very well run on DOS even if they need a Pentium. They probably won't run though, at least not playable, on ao486 !

Glad to see I'm not the only person with monitor sync issues. I find cache version 40 runs fine for me using normal MiSTer file if set at 90mhz. Anything later than that I can't get to work because of monitor synch issues with the MiSTer file. That includes other cores & even main menu, tested with multiple resolutions & vsync/scaling optio...

I can't post a link here as nefarious scumbags who do not legitimately own every single piece of software used would be inclined to download it illegally

Maybe it's something to do with me having activated the VGA scaler in order to be able to use filters. If this had the internal filters I'd just use HQ2X. This monitor is prety damn robust when it comes to displaying signals (I did have it set for 1600x1200@60 over VGA but the ao486 core looks nicer with 800x600). It's the HP LP2065 monitor. Unfort...

Oh, sorry, I was assuming there was room on the SD card for a backup, so you'd just copy from/to SD without involving network traffic, but I see your point...the slack space on the VHD is ignored by Ghost but copied by Linux. Maybe your strategy is faster (on a clean install, at least) after all. =) Yeah, even on my modern Win10 PC I keep the OS d...

Just one tip - rather than cloning in-skin, it's far easier to just ssh into the MiSTer itself (without the vhd mounted or the core running, naturally!) and just make a backup/copy of the vhd from the command line. (It's also FAR faster.) Thanks. My idea was to make the Windows C: partition as sleek as possible & be able to backup that to the ...

For anyone interested, I got 98lite "sleek" and "micro" installed & booting. Used 98SE retail, and 95b retail (cache 37 tested -40 failed). Never use 95C for 98lite install. Quick guide for how I did it (you can do it differently, but read for important error info): Created VHD 4gb in Windows. In ao486 used fdisk in from 98S...

The "out of sync" issue with cache 41 wasn't limited to ao486 core - the actual menu screen wasn't showing after turning the MiSTer on so I couldn't see anything to actually access ao486 or anything else! Changing back to the old MiSTer file sorts the menu out, but cache 41 complains it can't see any boot devices. EDIT: Oh yeah, forgot t...

With the new MiSTer files for cache 41 my monitor says "signal out of range" (set at stock 800x600@60). Even main menu isn't displaying.

You can mount a VHD in Windows using "Disk Manager". Just assign it a letter & you should be able to r/w whatever you want.

Glad your new DE10 nano is working. Stripped mine down, definitely HDMI is dead. I managed to get 1600x1200 out @60 over VGA. It's a bit annoying to lose ability to connect monitor & TV at same time, but I'm now thinking it's not really worth £110 just for that functionality. Maybe I'll stick to VGA. Are there any other reasons I'd want/need HD...

I'm usually pretty careful. I guess I was careless plugging the HDMI cable into a monitor while it was turned on.

Yes, was a full MiSTer with IO board. I tried a fresh install on another microSD & same thing, no signal from HDMI. My only option now is to dismantle the MiSTer & rebuild, I'm hoping that "resets" everything. I recall my dad's PC stopped working after a thunderstorm once. My guess was the BIOS was corrupted & told him to pull...

I wonder if you could use DriveDroid on an android phone to simulate a USB CD/DVD drive that'd work in Win98SE. That way you could just eject & insert bin/iso's on the phone to swap disks.

There's always something fascinating about pushing something to it's limits & beyond. The MiSTer itself is a good example of hardware constantly being pushed farther & farther. Look at what the humble c64 can do in 2020 - modern demo's would've seemed impossible back in 1982 (& wouldn't have been). If you get you're kicks out of just us...

This just happened with my board after connecting to a new monitor HDMI has stopped working altogether. VGA still works (I want to use HDMI for certain cores on a different display).

Will investigate some more, no doubt whilst uttering innumerable obscenities.
