At the moment, I have a N64 modded with a PixelFx HDMI converter, a GameCube with a MKII EON which is just a composite to HDMI converter that plugs into the back, and a PS2 with a really shitty standard composite to HDMI converter that is powered by one of the PS2’s USB ports. All of those, and a couple of non-retro consoles, feed into a 7x1 HDMI switch and then into the TV. And the TV outputs all the audio to a sound bar. I just finished modding the N64, but I have another PixelFx for the PS2 because the lag of the converter is really starting to piss me off, and an untouched Wii sitting in the closet.
Modding the consoles is just what I prefer so that they work on modern TVs, and it gives me something to tinker around with. The problem with that route is that the mods can be expensive, paying someone to install them is really fucking expensive, and even if you have the know-how to install them yourself there is still a chance you can brick your console (there is also the rotting carcass of an Xbox in my closet, but we don’t mention it after 3 years of headaches). However, you said that you already have a TV with composite and component hookups, and it looks like there are composite and component switches like what I am using for my HDMIs. That would probably be the best way to go for you, and it looks like you could get one for about $30 USD. I dunno if a switch will degrade the signal quality at all, but I haven’t noticed any with my HDMI switch and I think I got mine for around $40 USD. When it comes to quality… Look, the consoles and their games are dated. No amount of lossless converting or upscaling is going to make them look like a game on the PS5 or Xbox Series SSX Tricky whatever the fuck it’s called. You’ve got some consoles and a TV that you can plug them directly into, that’s about as good as it’s going to get without diving through a trash heap to find a CRT. If you do end up getting a component/composite switch, maybe get 1 OSSC between the switch and the TV if you really want one. You don’t have to spend tons of money on something because some nerd on reddit insists it the “best and only way to experience retro games” just do whatever works best for you and remember to have fun











Dokapon Kingdom
It’s like Mario Party, but with RPG elements. Start with classes like warrior, mage, and thief, and more classes unlock later on. You use dice to decide how many spaces you move around the map, and fight bandits and orcs and stuff. Every now and then the king/princess will give a quest to go and take back some stolen things from a bandit. First person that can land on that space fights the bandit to get the loot back, and then you have to bring it back to the castle. Other players can land on your tile and fight you to steal the loot. Towns around the map have a boss monster and if you can kill it you “control” the town and get passive income, other players can steal the town for you. Mario Party is known for ending friendships, but it doesn’t even compare to the levels of cutthroat betrayal that happen in Dokapon. 10/10 highly recommend
