@PlaneVuki, I am not one of the dosbox developers and will not test this for you on plain 0.74-3. You are free to use a SVN build or one of the forks or not, it's your choice.

I did a few test with 86Box 3.2.1, configured to emulate an Amstrad PC1512, to try to validate some things. - Maupiti Island has the same box around the mouse cursor with 86Box as in DOSBox-X - Iznogoud still only shows CGA after selecting Amstrad - The Bob Morane Chevalerie 1 and Jungle 1 games …

I tried it with dosbox-svn (development build), but I'm fairly sure it should also work with the standard dosbox 0.74-3. Did you use "machine=cga"? Because it will not work otherwise. You also want to do it after you start the game. There is no on-screen indicator when you press F12, and depending …

Iznogoud is another game that advertised PC1512 support, but like the Bob Morane games only seems to display CGA. Filename tatou_000.png File size 2.92 KiB Views 3725 views File comment Video selection Filename izn1fcga_000.png File size 8.34 KiB Views 3725 views File comment Game in Amstrad mode

Maupiti Island indeed has an Amstrad mode and it looks like the games EGA mode. Except that there is a "box" around the mouse cursor in Amstrad mode and not in EGA mode. Also, the Amstrad / EGA modes look better then the Tandy mode in this case. The Tandy mode appears to use a lower resolution, …

A separate thread on games claiming (and actually supporting) Amstrad PC1512 graphics would be better instead of posting it in this thread.
Re: Games that show 16 colors ONLY in Tandy / PCjr mode?

There are various titles that claim Amstrad PC1512 support, but all it seems to mean is that the game will run, not that it will use the Amstrad graphics mode. For instance, there are three "Bob Marone" games by Infographics that claim PC1512 support: - Bob Morane: Chevalerie 1 (offers CGA, Amstrad …

As mentioned, with "machine=cga", DOSBox defaults to RGBI, unless it detects that a game is trying to use artefact graphics in which case it will switch to CGA composite. There are some key combinations that allow you to change some settings, once the game is started. F12 = cycle between Auto, …

If your looking for other games that only supports 16 colours on Amstrad, there is a bad and obscure boxing game called "Frank Bruno's Boxing". If you don't have the Amstrad graphics you will only get black-and-white CGA. https://www.mobygames.com/game/dos/frank-brunos-boxing There is also a Sierra …
Re: Any DOSBox branch/fork with expansion card and ROM plugin support?
Posted on 2022-03-12, 15:27
DOSBox-X has support for loading the original PC/XT ROM for the integrated BASIC, and you can also load a VGA BIOS ROM, like the Tseng Labs. But no support for loading arbitrary ROMs.

You can have a (possibly per-game) dosbox config file with an [autoexec] section where you do the steps such as MOUNT or change drive or run DIR. No need to use an external script. e.g. [autoexec] MOUNT D: D:\ D: DIR In addition some dosbox forks (e.g. DOSBox-X or -staging) have support for AUTOTYPE …
Re: Aces of the Pacific, MT32 and DOSBox and DOSBox-x memory issues
Posted on 2022-02-26, 10:00
I don't use the full dosbox or dosbox-x config file. Way to many options to dig through. Instead I use a minimal per-game config, with ONLY the options that I changed from default. That makes it easier to see what you changed.

I have the game and it runs just fine in DOSBox-X (SDL1 or SDL2) on Fedora Linux 35. I also tried it with DOSBox SVN, and apart from the missing MT32 sounds, it started just fine. I don't have any special settings either in my dosbox config file.

I did not try vanilla DOSBox, but it seems to work fine in DOSBox-X SDL2. The only thing I had to do was increase the cycles a bit and it ran fine and keyboard input into the Hall of Fame worked.
Re: How many MB of VRam are emulated in DosBox?
Posted on 2022-02-13, 18:23
With the default S3 Trio64, dosbox defaults to 2MiB VRAM. And standard dosbox does not have a setting to modify this. Some forks have a "vmemsize=" option where you can specify other sizes. For instance for DOSBox-X, have a look at this wiki: https://dosbox-x.com/wiki/Guide%3AVideo-card-support-in- …
