RetroArch Port

Hello

Mentore ported RetroArch (1.19.1) and I just noticed today, which is awesome.

I installed "yum install SDL2 SDL2_net" it runs but I don't know if the cores (emulators) need also to be ported, or it will be download the cores from a site.

I tried to download the Core list from the app, but it is not downloading. Remains in 0%.

Anyone here with more experience with RetroArch?

Regards

Hi Martin,
this I have to investigate deeper. I also tried to download some core and, looking at the RetroArch homepage, it almost seems like cores have to be ported too. I'll have a look at what retroarch cores are - but many things point me in that direction (last of them, there are github repositories for cores).

--- Quote ---What RetroArch is¶

It runs programs converted into dynamic libraries called libretro cores, using several user interfaces such as command-line interface, a few graphical user interfaces optimized for gamepads, several input, audio and video drivers, plus other sophisticated features like dynamic rate control, audio filters, multi-pass shaders, netplay, gameplay rewinding, cheats, etc. Settings are also unified so configuration is done once and for all.

In addition to this, you are able to run original game discs (CDs) from RetroArch.
What RetroArch is not¶

RetroArch is not a computer program that includes all consoles and games. It is not a service that allows you to download copyrighted games or content. It is not an application that will cause you to modify the application to the platform on which you will install it, but in order to run unsigned applications on some platforms, the default firmware needs to be modified.

So yes, it looks like the cores have to be compiled for our platform and perhaps some porting. Our 8.3 DLL naming makes these things more then trivial.

Hello Mentore

I don't know if you can port some of the basic cores for NES and SNES that are very common and don't require a console BIOS to be downloaded by the user.

Hi Martin,
the next few weeks will be truly a handful both at work (where I have an ArcaOS VM) and in theatre, but I'll see what I can do. RetroArch would be really cute to have. It was tricky to port it due to its SSL libraries which rely a lot on IPv6 but I managed somehow - and I feel OS/2 would profit a lot of a new TCP/IP stack (which, I'm afraid, we will not see).
