Sid1968 Posted April 28, 2020 Share Posted April 28, 2020 (edited) As of today, RetroPie version 4.6 officially supports the Raspberry Pi 4, so that the corresponding image file is now available for download under this link: https://retropie.org.uk/download/ All users of the prereleased image files can update their RetroPie Version by: sudo apt update && sudo apt upgrade -y && sudo apt full-upgrade -y && sudo apt autoremove && sudo apt autoclean cd /home/pi/RetroPie-Setup/ sudo ./retropie_setup.sh In the menu: Update RetroPie-Setup-Script Back in the menu: Update Cheers Sid Edited April 28, 2020 by Sid1968 1 Quote Link to comment Share on other sites More sharing options...
tmop69 Posted June 8, 2020 Share Posted June 8, 2020 Has anyone tested the new V 0.16.0 (May, 25th 2020) of TI-99/Sim? The changelog reports "Changes to better support RetroPie setup & joystick usage". Quote Link to comment Share on other sites More sharing options...

Don't tell anyone but I know classic works and besides, when I see that MAME, I think of lame. But I just stick to what works great for me but I'm must disclose, I've never tried the mame. Only because of why as listed above. Quote Link to comment Share on other sites More sharing options...

Sid1968 Posted June 25, 2020 Share Posted June 25, 2020 (edited) RetroPie 4.6.2 on the Raspberry Pi 4 uses the Linux distribution Raspbian Buster. A new update from Raspbian Buster leads to sound problems, since the firmware that is installed does the audio processing in a way has newly regulated that Raspbian Buster can not handle it. There are options in the emulation station settings under this link to change, but then they only apply there and not under other Linux-based applications. BTW... none of them worked for me. https://retropie.org.uk/forum/topic/26628/audio-issues-after-latest-raspbian-updates/2 In order to basically restore the previous, working state of the audio processing, the file cmdline.txt must be edited. To do this, remove your SD card from the Raspberry Pi4, insert it into a card reader and open the file "cmdline.txt" with a text editor. Now add this line to the end of the existing line: snd_bcm2835.enable_hdmi = 1 snd_bcm2835.enable_headphones = 1 snd_bcm2835.enable_compat_alsa = 1 Finished! This method has the advantage that updates and new firmware can be imported again at will, because the changed audio settings in "cmdline.txt" on the entire Linux level are independent of Changes due to updates and new firmware apply.

I do not want to use the keyboard, since the Raspberry is in a GPi Case. ? The TI99 Sim was the only system on the RetroPie distribution that needs a keyboard to select/run/restart games. The C64, Spectrum, Colecovision and Intellivision have a "virtual keyboard" that allows to run/restart games using only the joypad. This solution was also implemented in the PSP port of the TI99 Sim. For running games, acting like a "console" is really comfortable. ? Quote Link to comment Share on other sites More sharing options...
jonecool Posted August 8, 2020 Share Posted August 8, 2020 (edited) I'm working on an interesting little setup, a Modern Retro Computer. It's a Computer console with keyboard+trackpad with a Raspberry Pi 4 running RetroPie+TI99Sim and a USB 3.5" floppy drive connected. I thought it would be possible to read/write floppy disks from TI99Sim, but when I try to save "SAVE DSK1.[NAME]" I get an I/O ERROR 60 response. Is there a configuration setting I need to enable to allow reading/writing to emulate a disk drive? I haven't found any info. on this yet. The goal, is if the save works that I find the location where the file was saved, then create a symbolic link to the floppy drive. This is mostly for nostalgic reasons, nothing more. My end-goal is to build a single console that can emulate multiple systems in a retro-style configuration which utilizes modern hardware components. Here's a link to my current project info. if interested. Planning a video on my YT channel later this week once I make a bit more progress. Any help on the save issue would be greatly appreciated.

Hi Mate, i enjoy your youtube channel. ? Without knowing TI99Sim in detail, I believe I can say that your project cannot be realized with it. I myself had a similar idea under this post: As a joint project of this forum I would like to create a guide: "How to run the TI-99 / 4A MAME Version on a Raspberry Pi 4". The emulator with which the project would be realized is MAME. In the first post I describe what the goal is. Extra wishes are welcome. So far, I haven't managed to 1. get Mame up and running with the desired parameters and 2. write a start script. Unfortunately, there has been no help with it so far ... although one of the Mame developers is active here in the forum and should actually have an interest in the project. But maybe you have the desire / knowledge to help achieve the goal. Cheers Sid ? Edited August 9, 2020 by Sid1968 Quote Link to comment Share on other sites More sharing options...

It's always fun to create new videos and rarely stressful, but in this case slightly so. I'm not having the same exact difficulties. I can definitely launch the TI-99/4A using TI99sim within Twister OS (RetroPie installed under PiOS with a pretty UI). I was also able to use the ti99sim disk command once to create a TI disk but have been unable to do it a 2nd time. Not sure why at this point. I'm keeping all my notes on the MRC page should anyone want to jump in and help If I'm unsuccessful at getting the TI to work soon, I'll move on to other consoles, DOSBOX, etc. and use them for my next video. However, the TI is the first machine I ever owned and hope to demonstrate the concept here first. But, it's not the end-goal -I want to run as many as I can on the Pi 4. I plan to demonstrate consoles running on this Modern Console in the future. May start looking at my 2nd computer soon, the Amiga. Then maybe others will show some interest and help with with suggestions/recommendations. I just like the concept of having a single console that looks semi-retro, utilizes some classic components (3.5" floppy, CD ROM,etc.) but running potentially 10-20+ different classic computer consoles on a single box. For the space-impaired, such as myself, it's a great option. Edited August 10, 2020 by jonecool Quote Link to comment Share on other sites More sharing options...

(I do not have an RPI4, but came along this performance matrix https://ninerpedia.mizapf.eu/en/ti99/mame/mamereq) I am still troubleshooting my real iron Geneve 9640 RGB video output, but in parallel also run the MAME emulation on my PC to see if I can everything as on the real iron (need to sort out the RS232 connection, saw some write-ups and to sort out the mouse connection for now and how to maximize the screen, but should ask these in another forum). The TI/SIM I mainly used it on my RPI3B+ for gaming (together with MSX, NES, SNES, MAME/Arcade games, etc.), e.g. if we have a gaming competition like Bounce N Pounce, I am checking the other versions, like Bump N Jump on the NES (I have not used the disk-access control, I think the other emulators are a bit easier to use it) Quote Link to comment Share on other sites More sharing options...

Mame runs with me. But as soon as I use parameters it doesn't work anymore. However, I am not a TI-99/4 expert and cannot script either. That's why I need help on the two points mentioned above. I had already described that in the first post of the thread. ? Edited August 10, 2020 by Sid1968 Quote Link to comment Share on other sites More sharing options...
