MiSTer FPGA Forum

With latest core update (20201128), CRT support it's work again. Thanks!!

Testing some demos on Atari 800 core I found a lot do not work, tried the same demos on MiST core and they work there, so something must be broken on Atari 800 Mister port. Tried old Atari 800 cores but did not improve matters.

Try opening an issue on the Github with examples which of the demos that work on MiST aren't working on MiSTer.

Might be worth running acid800 on mister to check, it should all pass

Is there a step by step guide on how to do this? I have the DE10 set up with the atari core. I have three xe ROM files and don't know what to name them or where to put them.

Only see one fail with the current core and framework.

I can't load any .ATR .XEX
.CAR .ROm .BIn works perfectly.

Anyone can test it?

thx

At first, I was having similar issues when tinkering with the different computer cores, I then found the cheat sheet (linked below) to be a tremendous asset.

My fault. I loaded the .ATR and I forget press F10. sorry . all works like a charm now.

What exactly does the Win key do in this core? I can't find the info on this. It makes taking screenshots with Win+PrtScr practically impossible as the graphics get all messed up while the Win key is held.

Hi,

I am trying to run Yoomp! (http://yoomp.atari.pl/download.htm) on this core. I tried all kinds of RAM and BIOS settings, but it always crashes the core after the second loader (with white background). Has anyone run this game successfully?

I have no problems running by hdmi and with the 128 MB ram module in the MiSTer

When I tried, it would not even start with the Basic BIOS enabled. What version did you use?

this game does not use BASIC, you must use the F8 (Option) key:

"After mounting the disk, press F10 to boot. Some games don't like the Basic ROM. Keep F8(Option) pressed while pressing F10 to skip the Basic".

I use the Atari800_20210228.rbf

Thanks. I was thinking that the OSD BIOS option should be used to disable the Basic ROM. It now starts

I'm having problems with Galaxian game on the Atari 800 core for Mist and Mister. The joystick is not detected. I tried using the swap option in the core.

Do you mean the 1982 Galaxian by Atari? I tried a XEX version of the game and the joystick did work. Which version of the game did you try?

Yes, the Cart version. I will try the XEX version. Thank you.

I think the cart version could be the 5200 version, don't know how the analog controls are handled. Make sure to try the 400/800 version.

Those who are not familar with Atari 8-Bit Computers and it's behaviour and meanings of the "special keys" (Start, Select, Option) might use the patched system rom, which I found here: https://atariage.com/forums/topic/20688 ... nt-4333535 The patches are:

• Hias' higshpeed patch to allow higher SIO transfer rates https://www.horus.com/~hias/atari/#hipatch

• Alternative math pack (might be incompatible with TurboBasic)

• Reversed function of the option key (normally you have to press OPTION while booting to disable Basic)

EDIT: Oh, just discovered, that - in contrast to the MiST version - it isn't possible to select another OS as they're statically build-in.

I tried the XEX version of Galaxian for the Atari 800XL but is not working either. Please tell me what setting are you using or where to get the working XEX.

Thank you.

BIOS: OS A
RAM: 64K
Start game with F6
Works with my USB2DB9 Monster adapter.

My Xbox 360 Arcade Stick USB is still not working in this game. I guess is the core. Thank you.

I had a similar problem with the atr versions I had, even with zeen's helpful settings.

However, I had a lot more success with a copy from http://www.atarimania.com

I've been quite frustrated with this too, trying to capture some of my own screenshots of some of these classic games.

Reading the doco from the developer of the original core, Mark Watson, the Windows ket performs the same functions as the Atari Key on an original keyboard. What that key is supposed to do on a real Atari I don't know but if you find a way to disable it, let me know.

it probably has to do with this:
https://github.com/MiSTer-devel/Atari80 ... +held+down

according to the comment:
"pause as WIN is held down"

... it's a shame I don't know how to compile or rebuild that :/

Hi,

Disclaimer: i am new to this

Tried to play some games, but failed to play with keyboard, as I have no joystick at the moment.
I was doing the following: "Map Atari 800 buttons" -> assigned up/down/etc. to keys on the keyboard.
Pressed Num-Lock until it shows joystick 1 (or 2, tried both). Fire-Button works, but I could not get up/down/left/right to work and I don't know why?! Tried it with several games and different key-mappings, but no luck. Can anyone help?

Thx,
Ray

I've just tried the default remap (cursors+Z) + Joystick 1 in Alley Cat & Ninja and it works no problem. What games have you tried?

A lot, 20-30, must be making a mistake somewhere. Just found out i can connect my xbox one controller via usb, happy now

Thx, ray
