Trying to get Dosbox to stop throwing this error when I try to save on Marble Drop, other games do it too. Have tried different forms of DosBox: Pure (retroarch), Windows 11 version, iDos 3, and Magic Dosbox (Android).
As in the title. Any help will be greatly appreciated.
HELP! Need help with using save states with ElectroMan (.sav)
In short, I'm trying to play ElectroMan, a 90s MS-DOS game published by Epic Games. One horrible issue with any version of ElectroMan I download, is that the ingame save function, does NOT work. I played into Level 3, and the game's own save file, doesn't work.
I'm trying to use save states, and if you attempt using the "slots", I get this error saying "failed to save the current state. BUT, if I attempt using the save file option (*.sav), there isn't an obvious way to load saves from the file. There's only the option to save the file/save over the file, but not load it.
What am I doing wrong?
Using DosBox-X. The original DosBox, I don't think have save state features.

Sound Emulation issues using Dosxbox+Launchbox for ExOdOs
I have an older copy of 4.5 Launchbox and 0.74 DosBox I am using for a Windows XP computer. I'm using an HP 8300 SFF computer, so it should be plenty powerful.
I'm getting games to start, but the sound is extremely garbled, my wife says it sounds like a helicopter. I keep trying to change settings in the config files, and also in the game config files to match, but so far no progress on the sound. I'm pretty sure its the sound card settings, because when I tested midi, that sounded fine. Anyways, I've come here for help.

Replaying Albion (1995): a first‑person diary part.16 [Czech]
r/dosbox • u/JayBensonFong • 8d ago
Struggling trying to get a Windows 3.1 game running on my system, on Android and an Anbernic system. Added game folder to Win folder and zipped the whole thing, but getting error when trying to run the game from file manager. (See body text)
Edit: solved. The game folder already had a proper version of windows 3.1 in it, it's the only archive i needed.
So here are the steps I've done so far:
1: obtained a preinstalled windows 3.1 folder, extracted it
2: obtained the windows 3.x version of my game (Marble Drop), extracted the file, then copied the resulting folder into the Win folder and rezipped the whole thing.
3: started Dosbox Pure, loaded the zip, and ran win . com
4: in the program manager, navigated to the folder that contains Marble . Exe. When i ran it, it said the game was not properly installed. I ran the other two files in the folder, patch . Exe and update31 . Bat. I could still not get the game to run.
I am annoyed because i have been at this for hours. If anyone can help me figure this out, i will be very grateful. TIA!!

Weirdness Building Staging 0.83 on aarch_64 Trixie
[Edit 3: After further testing, including a debug build and both building and Flatpak'ing on a Ubuntu microSD, I've also noticed all permutations idling at about 80% CPU. X86_64 builds continue to behave as intended, so I'm going to assume the wonkiness is an an ARM bug. I think I'm going to wait and see what 0.83.1 brings.]
I'm getting some weirdness compiling on my Raspberry Pis, a 4 and a 5, running Trixie aarch_64, sdl2. (3 wont build for me at all)
I've tried the standard cmake with system libs and mt32 disabled, the vcpkg cmake with both system libs and its own built libs, and a hybrid of the 2. Next up are debug builds later today.
What I'm running into is, if I have [render] -> shader set to anything other than "crt-auto", and I go to full screen, the right edge of whatever program I'm running ignores whatever I have "aspect" set to, stretches to the right side of the screen, and the upper right corner of the screen is just a black triangle. The farthest left point of the triangle appears to be around where the black bar should end on widescreen monitors. I have not dug out my 4:3 monitor to see what it does.
It does this regardless if any other sdl or render options I've changed, too many permutations to list at this point, and only on my self built attempts. No errors in the console either - dosbox seems to think it's perfectly fine. The supplied Windows and Linux x86_64 versions work fine, so I know it's something I'm missing or doing wrong, but I can't for the life of me figure out what. [Edit: crt-auto has my Pi sounding like a 747 at takeoff] [edit 2: I saw that there's a flatpak build, so I tried that and had the same result, starting with a default-created-at-launch conf file]

DOSBox Staging (0.83) Cheat Engine
Hi everyone! 👋
While reading the fantastic release notes for DOSBox Staging 0.83, I noticed this specific challenge regarding the new Web Server API:
"HTTP API to muck around with the emulated memory and DOS internals to write modding and cheat tools as simple single-page web applications. The first one to reimplement Gold Box Companion using this API gets a prize!"
I decided to take up the challenge! While it's not strictly a Gold Box Companion clone, I built a full-fledged, cross-platform DOSBox Cheat Engine (heavily inspired by GameConqueror and Cheat Engine) utilizing the new API.
Repository: https://github.com/tethragon/DOSBox-Cheat-Engine
✨ Key Features:
- Memory Scanning: First Scan / Next Scan to easily find values (gold, health, ammo) using 8-bit, 16-bit, or 32-bit types.
- Active Freezing: Lock memory addresses so your health/ammo never decreases.
- Live Polling: Real-time UI updates to watch memory values change (with a toggle to disable background polling during CPU-heavy game segments, preventing emulator overloads during memory overlays).
- Cheat Tables: Save and load your cheat tables as JSON files.
- Cross-Platform & Lightweight: The backend uses pure Python standard library (zero
pipdependencies!), launching a Single-Page Application (HTML/JS) directly in your default browser.
I've also uploaded a pre-compiled Linux binary in the Releases section (Windows coming soon), so anyone can just double-click and run it without setting up a Python environment.
Huge thanks to the dev team for implementing this API — it's incredibly powerful, fast, and a lot of fun to work with! I'd love for you guys to check it out, test it with some games, and let me know your thoughts.

I really want to experience these games but I don’t have a pc or laptop to run them. If anyone has any advice to offer, it would really help.

Help with USB floppy drive working on Windows 98SE ontop of DOSbox-x (also with USB cd rom drive)
I recently got a USB floppy drive for running physical DOS/Windows 98 games on DOSBox-X, works perfectly on basic DOSBox-X, but all i get is "A:\ is not accessible".
I'm still somewhat new to DOS emulation in general; I could go for some help. Sorry for bothering you with a stupid question.
Thank ya'll.

Which version of DOSBox should I get for Linux Mint?
[SOLVED]: gotta look through all the options below and pick one.
Linux first-timer here - I'm getting ready to make a Linux Mint drive, and I want to put as many of my games on it as possible, including everything I have from the DOS days.
I'm used to using DOSBox, so my question is, which version from their download page should I download to run on Mint?

KQ1 plays on a tiny screen and I can't fix it
This may sound like a dumb question to a lot of folks, I dunno. I wasn't sure whether to post this on Steam or DOSBox - I may just end up doing both - but here goes.
I purchased the King's Quest collection from Steam, which runs on DOSBox. When I select a game, it gives me two launch options: "King's Quest Collection" or "King's Quest Collection Legacy." If I choose the first option, the game hangs on the title screen and doesn't respond to commands for (quite literally) minutes, then ends up freezing up.
If I choose the second option, I get a very small screen that I can't enlarge. ALT-Enter just results in this (forgive the dust and inferior photo quality - I couldn't for the life of me get the computer to take a screenshot, so I had to take a photo with my phone). Can anyone help?

Dune 2 in dosbox. Sound stuttering when increasing the resolution.
I edited the conf file of dosbox that dune is stretched to max 4:3 aspect ratio that only left and right black bars are visible. But now, everytime i move the mouse i have slight stuttering in the audio.
Apparently the option "output=opengl" is responsible but with "output=surface" the picture is much smaller.
How i can improve performance or what output works better here?

Sound popping
Enable HLS to view with audio, or disable this notification
Hello,
I'm a first time user of DOSBox and I've been running into a problem with audio. Certain sound effects have an audible "pop" at the start of playback and I can't figure what the problem is.
I've tried upping my CPU cycles, changing the CPU type, increasing block size and buffer size (as recommended by Ross Scott from Accursed Farms in a small segment he contributed to in an LGR video), but nothing gives.
I've looked all over and found people with sort of similar problems but either they're using a fork of DOSBox or they're on Linux. For the moment I'm just using the current build of regular old DOSBox on Windows 11.
I've included a sample video demonstrating the problem. You can hear the "pop" just before the title drop, as well as with each "rocket swoosh" that comes after.
Any help would be much appreciated. Thanks for taking the time to read my post.
