I will reword it because if you don't need overscan for most games, you do for menu disks.
From the manual: Software Overscan There is a trade-off between emulation accuracy and performance. None: Normal video output, most video tricks (abusing the GLUE, the MMU, the Shifter), generally called "Shifter tricks", are not emulated as there is no overscan check during emulation. This is actually enough for most programs, including most games, as overscan wasn't part of the ST specification, but many demos won't display correctly. Who watches demos anyway, right? Spectrum-512 emulation will...
I don't doubt it will for a second. :) I am set to STF (STType = 1) with Overscan emulation set to None. Settings file attached. As I say, I deleted and started afresh with only a few changes. I did this because on updating, after not having touched STEEm for more than a year, I was having issues where the emulation wouldn't even start. There seemed to be redundant settings that disappeared when I used the fresh settings file.

Hi John, Some of the supposed problems depend on machine settings, typically menu disks run better on STF. But your report on PP49 is no spam, emulation will be improved thanks to you!
Ah, Auto 94 is fine though now. Sorry for the spam(?). It's a running commentary I guess. Wait, you can edit posts?? Damn. OK, well PP 49's border is fixed but it's still flashing now. Nah, border's broken again after a little twiddling with settings! Just to how I like things, nothing complex. So's 94 again. That's enough for one day; goodnight!

Nope! Full reset and all default settings and it's still happening. I'll leave things in your capable hands for now then, Steve.
Now Automation 94 is wrong too. Am I'm going to have to reset the settings file again? Sigh, OK. Let's try again.
Oh, and I almost forgot. The ST Aspect Ratio setting doesn't work properly either. On boot, it stretches the main window too much and when you click on the settings window it goes back to how it should be. With the setting turned off it keeps the correct size. Hmm, actually toggling it seems to change the window size depending on what's being drawn to the screen at that time. I'm talking about loading from a cold boot though so that might just be an anomaly. What's more important is it's not remembering...
...Pompey Pirates disk #049's menu seems broken? The flashing (!) and the bottom border is half cut off. I've tried multiple settings and even reset the steem.ini file from scratch. It works as it should on ancient SainT! That's why I think I must be doing something dumb. Cheers.
Hi, What's changed since 2020 is that you left click to enable/disable and right click for options, and the size limit is larger. You need to reboot emulation and for me at least the C drive appears. For the record Pasti mustn't be enabled.
I am having the same issue. Its not clear from the instructions how to add a disk. and your comment above is straight out of the manual, it seems. open disk manager. right click on ASCI. Click enable. Browse to add the Megafile image in the ASCI directory. Click OK. and then? nothing happens. restarting Steem does nothing. No C: drive appears. What step did I miss? Thanks, Kelly
some code clean-up
SSE_AUTOUPDATE
hello again,wireless mouse doesn`t work in pc today steem 4.20.worked ok yesterday,works fine in windows 11. played with all settings-nothing.any ideas?? cheeers!!
Can you get the atari st floppy sound from Saint emulator? Cant find the sound in Saint emulator thanks!! :)

R10 Fix SCP to STW conversion 21 February 2026
tag release 4.2.0 R10
bugfix R10
Hi, It's a legit request, because there are many updates (one more coming this weekend!)
It's a late thank you but your work is very appreciated. I've think about another "feature" that could be great : Instead of a zip folder, having an update programme like many others could be sympathic : Whith launching an exe, finding the previous version of the program, it simply update the program, concerving the configuration (folders, joystiqu, and so on ). Regards

Hi Steven, the latest beta works fine. Thanks Regards Cyprian
Hi Cyprian, You can send me the binary to donmegacool at hotmail.com
I see strange characters in TRACE.TXT. The app was compiled with VASM, maybe there is something wrong with label's format in .PRG file
Hi Steven, my clean GEM test app causes SteemDebug SSE 32bit to crash and close, and SteemDebug SSE 64bit version shows "System Error" - "System exception $C0000005 at $0000080E080E1008" It works ok under Steem64D3D and Steem32D3D. I can share the source code and binary but not publicly. Just let me know how to share it (email, PM forum, discord, etc). Thanks Regards Cyprian
Minor fixes
FYI, Just installed Steem_SSE_Beta_421R1.7z and as you indicated, the Window Position is now operating perfectly. Thanks for all your great work.
great, thanks
Hi Steven, I wonder if TRACE.txt checkbox could be moved from Startup to the Debugger (e.g. to SSE menu)? To be honest, I forgot about this checkbox and in the new version of Steam (where this checkbox was unchecked) I was wondering why the trace file was not generated. My first thought was that something was not clicked correctly in the LOG or SSE menu, or Control Mask browser. Thanks Regards Cyprian

trunk adapt Copyright year
Hi Steven, would it be possible to separate "borders" settings for color and monochrome monitors? In case of color monitor, the border can be useful - there are some demos showing effects in overscan. But with SM124 the border is useless to me. So, every time I switch from color to mono or vice versa, I have to toggle this border option, which is a bit tedious. Thanks Regards Cyprian
Hi Steven, I completely forgot about that. Thanks a lot, it works fine for me.
Hi I think you already had this request and I addressed it: If you add this line in the [Main] part of steem.ini: MonochromeDisableBorder=1 Borders will be off in monochrome mode, except if you switch them on after the cold reset. You can also use different configurations instead. Does it not work?
Hi Cyprian Thx for the report, I'll fix that in next release.

Hi Steven, I noticed something interesting - Stek Magazine is crashing the Steem application: https://demozoo.org/productions/91490/ I'm not sure if this is a problem with bad MSA file or not. Could you please look into this issue? Btw, the same thing happened with the previous version of Steem. Thanks Regards Cyprian
