I built a retropie as my Wii is getting old and does funny things now that it's been modded for awhile. Cheaper, better, smaller.
I had random crashes of homebrew software now and then. Some of it that was Internet-bound like the Homebrew Browser doesn't work properly any more, the servers are probably not maintained right now. The emulators and USB loader are set-up tho, so adding new games is just a file copy to that disk. For Wii games I use some Windows utility that manages that "Wii Backup FS" used for storing Wii ISOs but that again is an exact copy with some filename mangling.
Technically, none of these operations touch the Wii system software, my Wii boots to Homebrew Loader directly etc. The Wii menu is empty apart from the "Mii" and "Homebrew Loader". I wasted a week's worth of afternoons learning about and how to revamp the firmware and all components needed to have a hacked Wii.
Another interesting thing is that we played multiplayer DOS at job last Friday; Dosbox can emulate Novell networking that DOS understands through TCP/IP that modern host operating system understands, hassle free. We played Death Rally - I'm extremely good at that game and they were no match, and we played Warcraft 2 where everyone had problems with too snappy in game scrolling and dumb route-find algorithm where you need to micro your units because they're unable to walk around the forest with just click-to-destination. I also forgot that naval units will just sit there and fish while the enemy is passing right next to them, if you don't put them on explicit patrol they do not shoot at anything. Anyways - there is no RNG involved in the fight turns, the Humans and Orcs are perfectly balanced per unit basis for 95% of the units, and for buildings that produce upgrades. This means a high possibility of two of same dueling, meaning a clear 100% win for whoever fires first. The game did not age well I have to say, all the advancements that Starcraft brought in RTS world are missing...we did play Tides of Darkness and not BTDP which as I recall from single player campaigns back in the day, at least didn't have the route finding issues.
I overdid my naval units and had no means of defense when one sent dragons to harass my town and other managed to do a D-day with a bunch of ogres in his 3rd attempt. I've allocated a lot for farms and peasants because I was the only one with two gold mines on my island but the other one had grave route-find issues where peasants were unable to automatically mine. I got annoyed by the game and my incompetence and blamed everything on them playing two against one, attacking me in unison, etc
P.S. if you guys need some backups for any system go to
www.emuparadise.org . The site has no shitware and it's easily navigable, with download limits based on file at a time, not speed. I've been a part of that community and "worked" for the site back in 2002 when I discovered the scene after having a heart attack seeing the three yellow triangles coming together, hearing the cascading harp arpeggios with a label "(C) 1991 Nintendo" right on my PC
