@mitu I tried all the commands listed and nothing seems to change the look other than removing the -f, adding in the -4 and choosing CEA-4 as the video mode. The --scale2x did what it usually does, gives that rounded look. --scale=n (interger scaling) did nothing, and niether did -NTSC, -PAL

So this is the end result. It looks odd with all the color and no black borders on the sides, but it runs great and has the 4:3 size ratio.

I don't know what else to do with this, seems odd that it does this. I can live with it if there is no other choice.

just closing the loop here, for 1. i didn't figure out how to map the system's joystick fire button to a gamepad button but after some online searching apparently every TI994A game can be controlled solely by the keyboard - the fire key for Shamus is "q" after some trial and error (hold "q" and press the direction of fire). all good now!

@NewAtThis Can you try updating the ti99sim emulator from source and check again if the resolution handling is better ? It's been updated to the latest version, which was a major update.
Try to remove any video mode set through the runcommand launch menu.

@leitmotiv said in No retroarch for TI/99?:

Anyone know a workaround, or if ti99sim will eventually use Retroarch?

That's up to the emulator author to decide or another developer that can contribute the necessary code to the Libretro project. The RetroPie project bundles the emulators, but does not develop them.

@herb_fargus I'll be honest, I haven't got a clue what you just told me :(

Hi @KevinsHope

Follow the instructions on Retropie.org.uk to download and install the official image to an SD card.

Once you have an official image installed, try it again and see whether it now works.
