Provide a clear and concise description of the issue

Hello everyone!

I have seen in docs that you asked for help with the CPC and I am the official developer of cap32-libretro, I would like to help you in what you need because the emulator in recent years has experienced great improvements that greatly facilitates its use and enjoyment.

The first thing I have seen is that the version you include is VERY old, currently the stable version is 4.5.4 and the latest versions also include a trimmed screen to enter perfectly in 640x480 screens.

In addition we have been working on a game database, called clean-cpc-db (very easy to find a pack in archive) that allows you to click and play as it directly configures the keyboard to play by pressing START and not worry about anything else. As if it were a console.

I have put a lot of effort in bringing the CPC to the public and I would like you to have the best support because I love Onion :heart:

Steps to Reproduce

Current version suggest an abandoned crocods that a basic emulation and needs the use of keyboard and a version with many years of caprice32.

Provide any additional context or information that may help us investigate your issue

In short, my advice is to update the cap32_libretro build to the latest version which is perfectly stable. If you need any kind of help/support you have me watching this thread.
