Do we know how to oc the Lyra board mame is playable but a little oc would do wonders.
Updated now with mame2000
tips for mame 2000. Average around 26fps at start.If you put sound sample to lowest. Turn off game skipping and use screen full screen in video settings save global config. Okay put Audio adjustment on as some games will run crazy fast. This is now the best optimal settings around average 40 to 45fps.

Has anyone tried the new screen driver? Does it make a difference would like to know the screen improvement.
I havenāt tried 3-bit mode, but 16-bit mode did not result in a very noticeable difference. Maybe because I did not test with the right software.
Good news is that it doesnāt break anything.
Few of my notes: (these are scattered around on this thread)
-
If on Mac you can download the raw image from the āsd-raw-imageā in the google drive. and use balenaEtcher app to write the image to the sd card. sd-raw-image - Google Drive
-
You only need to use the windows exe program to erase the flash if you get the 256mb flash version of the lyra. So donāt get that one.. get it without the flash and you donāt need to do that step.
-
MX1.25 connector needed if you want to hook up wifi to lyra board.
Is there a document that contains all the FAQs for this project? Going through this thread to find the answers is sometimes a little much.

Unfortunately, I donāt think so. But that would certainly be helpful. At least for this everything is in one thread. For the MicroPython stuff, itās scattered around even more. 
I think a lot of the projects around the PicoCalc and other Clockwork devices could benefit from a FAQ, a wiki, or a step by step guide of some sort. For the most active stuff it might be difficult to maintain though, until things settle down.

All the best,

I have searched an read this thread at least 10 times. Very hard indeed.
Cheers,

EDIT: I gave RKDevTool another go!
Worked now. I have network!
Thanks!

I wonder if I missed some.
I canāt find that in the googler drive? Also not a newer raw-sd that this:

From what I can see in the source, it seems like the devicetree is missing the external sd card support. itās there in the image, thoughā¦
What puzzles me: how do we keep our personal files and preferences intact? Can we make a home partition for example?
Cheers

Iām hoping to use the flash on the 256Mb model AND the sd card for other things. (Flash might be faster ??)
Use the flash for what? I have MSWord documents that will not fit on that tiny bit of flash.
Iām interested in doing that as well, though I havenāt really tried yet for the built-in flash. Thereās no particular reason it couldnāt be done - grab the SDK, follow the directions, and add the changes from the git repo in this thread, and you can build your own image - even for the built-in flash if you want.
Iām currently working on getting an RTC I added working, and a few other things. I expect, later on, to see if I can boot from the flash.
you can store there hidden copy of pgp keys / bitcoin wallet and no one will ever find 
if I were forensics, that would be the first sort of place I would look. The RP2350 (pico2) would probably be your best bet as it has native SHA-256 built in.
Just sayin` 
Here are my suggestions for programs to add to the build. None of these is in the current build as far as I know. All of them are command line/text only programs. Some of them are handy utilities to have and others are productivity applications.
mc, cmus, neofetch, mailutils, ufw, tty-clock, calcurse, irssi, alpine, wordgrinder, sc, tpp, and gpg.
Thanks,
Chris
