note that for retropie emulation purposes, there is no performance/compatibility benefit with >1GB RAM on pi systems. RAM size is simply not a bottleneck.

the 4GB pi4 model is relevant for those who want to the raspberry pi OS desktop, or as a server, etc but emulators for the systems that the pi supports don't have large RAM requirements.

@sirhenrythe5th I'm not an expert so I'm not sure. I would assume that would also require a better gpu as well. I mainly use the Pegasus front-end and that got a boost in speed when I switched from a pi3b+ to a pi4.

Right finally got this working :)

To confirm, 3rd party images at the moe dont seem to be supported, but just wanted to highlight the official ''image'' download of 4.6 (found under pi4, https://retropie.org.uk/download/) also does not work and you will get a boot error occur

You can however get RP 4.6 to work! From official Raspberry Pi page, download the imager app: https://www.raspberrypi.org/downloads/

Using the app, there is an option to choose the op system you want to install, so retropie for us and then let it do its thing. It will format disk/write image in one go. Once you put the SDcard in Pi, it will boot, no errors whatsover straight into Retropie!

Note: If you use windows 10, there is chance the imager will fail to write, its a windows setting thats the issue and this is the fix: https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=267364&sid=f6d32a82c84ebcfacdc2b3f1536cc4c1&start=25#p1664662

With Pi up and running! just needed to load roms which are on my external ssd. (indeed, the following is correct proc: https://retropie.org.uk/docs/Running-ROMs-from-a-USB-drive/). The SSD was again working painfully slow and needed the fix mentioned (https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=245931) to sort that out.

Finally got RP working! in for a long scrape now for artwork before i can get onto some tweaking :)

I think it was one of the questions on the blog post from yesterday. It remains to be seen.

Q : How much higher are those peek currents?
A: Not vast, and of course DRAM current is only a small fraction of total loaded power consumption. But required a change nonetheless.
