If you run into problems with a particular game, I recommend that you do additional research on tweaking settings, trying a different emulator or trying a different ROM. For example, when playing Tekken 2 for the PS1, the video quality was very choppy and there were plenty of skipping frames. Based on my experience, more demanding games from platforms like the Nintendo 64 and PS1 may have performance problems. For example, I installed 12 video game ROMs and ISOs onto the Raspberry Pi 4.
The Raspberry Pi is essentially a less-powerful PC when it comes to emulation, so that may have some limitations depending on the types of games you want to play. Also, configuring the emulators to work with your hardware (ex: your controllers) will take some time as well, so keep that in mind. PC emulators will give you an endless amount of game options at your fingertips however, finding the right emulator and ROMs to run can be time-consuming. In theory, there are ways to play most retro games on any of these platforms, but some methods are much easier and cheaper than others. I’ll cover this more in the performance section. I noticed that these consoles run better on an old school CRTV, due to the analog being a direct signal, as opposed to converting to a digital signal.
