i may have found the PERFECT method to do this.
1. any computer with hdmi connection port
2. download andyos
3. download any emulator
4. connect consoles via hdmi
5. use andyos + screensharing/casting to cast your screen+computer over any wifi network and thus you can play any system anywhere
andyos is an android vmware [a software that runs android os at the same time as everything else on your computer]. it can be installed on mac or windows, and runs like clockwork. once installed you can log into your google account through the android interface. through google play you can install and play literally any app your phone or tablet can. LITERALLY ANY APP.
if you combine andyos with windows built in game mode [windows logo+g] you can record your screen, audio, and other aspects. it is important that you do not open too many things whie running andyos to make sure it doesnt lag.
also with andyos you can install things like the at&tuverse app to watch tv on your computer [believe me this is frustrating to try to do without android.] basically you can watch your dvr on the go. though i ran into some wierd administrator/parental control issues. you can even install emulator apps or games that are normally only available through google play+android.
[the following is a list of valueable apps for literally everyone and anyone, to skip to the gaming part of this type "hdmi" into the search bar and skip to the second entry]
this brings us to running any console through andyos, basically you can install the emulator for consoles [drastic for ds, my boy! for gba+gbc+gb, snes9x for snes+nes, epsxe for ps, ppsspp for psp]. these emulators are worlds better than the computer based counterparts. for computer though youll want pcsx2 for ps2, dolphin for gamecube+wii, and if you want a really good gb-gba emulator for pc you can use mgba [which is easier to use but can be difficult due to syncing issues with sound and video].
there are also very good apps only available on android [and not even on ios]:
"scanner radio - fire and police scanner" is an app that has police and emergency scanners provided by local citizens.
"letter scrambler" and "alarm clock plus *" [thats a star at the end] are two good apps, with the first being basically an app that takes random letters and gives all words possible from them [if you play scabble] and alarm clock plus is a special alarm clock app that allows you to set multiple alarms and use your own music to use as alarms [and yes you can put music and files into andyos and access them]
"phases of the moon calendar & wallpaper free" is a great app that keeps track of the moons phases for any stargazers out there.
accuweather is the most accurate weather app. "noaa weather officlal" is one of the best weather apps for severe weather.
"random numbers generator" [the icon has two red dice] is the most fun app for anyone who plays d&d, board games, or wants to place a bet. the app allows you to set parameters for mini and max numbers and exclude numbers and rng at infinitum or till the numbers run out.
[the following section is for texting/calling apps to get to the game console info type "hdmi" into the search bar].
tired of those annoying spam calls or people who just wont stop texting? or ever wanted to text someone but not wake them at 3am?
"text me: text free, call freee, second phone number" is an appa vailable through android and ios that allows you to have your own personal phone number at no cost. you will need to watch ads and complete some tasks [which give you a certain number of "points/credits" and these points are minutes. one credit is one minute and you can easily get hundreds of credits, and they transfer with your account so you never lose them. texts also never use points, and many phone calls dont use points.
truecaller is literally the best app you can ever download. that is a fact. it has a caller id feature and call block feature that can let you block any call listed under an unknown name. it also allows you to block texts. the blocking feature can be selected from all phone calls, and the app keeps a record of all calls missed, picked up, and sent; by name. the app even saves blocked people when you transfer your account, so no losing blocked spammers. it cannot block all spammers as they always use different numbers, but typically once blocked they never call again. trucaller is also free and costs no money so its a must have.
"send it later! sms scheduler" is a unique app that allows you to send text messages at a later time and/or day. you type the message you want to tsend and select the recipient then choose a later date and time [including the same day 1 minute later] and the message gets sent at that time. i love sitting around the table eating dinner and having sent like 16 messages to everyone in the room five hours prior with kitty faces. then while eating with my phone on the table and my hands fully visible i watch the chaos as everyones phones blow up and they look at me and everyone freaks the f!@# out. its also good for sending texts at 2am that dont get sent til 9am so you arent summoning the wrath of your s/o asleep in the other room.
now onto the ultimate gaming sessions. first of all you will need at least one hdmi cable. basically any gaming console can be plugged into the computer via hdmi. if you use a splitter you can plug multiple consoles in.
what you want is to also get a steam account. steam is a pc gaming app/program [arogram?] that has a giant ass gaming library. if your computer can run steam it is important you do so. what youll want to do is install steam and setup an account. then plug in whatever consoles you want to play on through hdmi. youll want to set up your computer to be used as a display for the hdmi. with that done and considering you have downloaded the gaming emulators above you are ready.
basically just find any device you want to game on that has screen sharing or device local connecting/wifi screen casting. using your computer simply cast/connect to that other device [making sure you can use a controller with it. with the ability to control your own computer wirelessly you can play games off andyos, steam, the console through hdmi, or the emulators you have on that computer.
now a more complex but WAAAY more effective method to do the above is to use the "team viewer/teamviewer" software. yes i know that is the software primarily used by "nigerian tech scammers", but it is also a program that allows remote control of the pc from any device through wifi. this is significant because you can connect from a second device, turn on your computer, enter the code, then leave your home. then as long as you dont lose your connection you can remotely accesss your home pc through team viewer and use literallhy everything on it. you can even black out the home computer screen so nobody in your home sees you messing with your own computer, or lock the device if you notice someone screwing around with it while you are out.
but basically [short of where to get roms, and if you want that info go to "chucknorris.com"] that is it. it is convoluted, but it works.
