Homemade Arcade Thread

[Anonymous No.2761542]

Hi /vr/.
>Be me, in 1st year of IT engineering school
>Find buddies interested in retro vidya
>Big conference at school
>Teachers tell us we've gotta do a project for the end of the year
>"Let's do an arcade machine guys !"
>Everybody's like "fuck yeah, let's do this !!"

Basically, we're gonna build a minimalist computer with a Raspberry Pi 2 with Arch running on it, program an interface so players can choose their game, have a wifi connection so we can put our own games on it and make updates, put high-scores online and shit but we have a few problems:

1) How can we use old arcade games on our arcade machine without running into legal trouble ?
2)When playing with two players on Mame on the same keyboard, we had a huge input lag on most games but especially Dodonpachi, and shit like this can ruin the game. Any ideas ?
3) We're gonna build our own arcade controllers for it. Any advice ?

Also, general arcade thread and thank you /vr/ troopers.

Your project looks that way.

Using a raspberry pi is fucking retarded. You have so much fucking real estate inside an arcade cabinet that you don't need a fucking microcomputer to do it.

>Input lag on some games
Becuase you're using a fucking PI

>We're gonna build our own arcade controllers for it, any advice

Go to something like Groovy Game Gear, buy buttons and switches, and then figure out how to rig it up. You could most likely just emulate keystrokes or you could setup like a breadboard .

This also isn't /vr/ in the fucking slightest.

Please don't build a shitty American-style panel with a bat top and a grid layout for the buttons.

You hear that everyone? Arcade games aren't retro.


To answer OPs questions, drop PI, get a couple of older desktops, get the buttons and shit and just solder them to either a gamepad PCB or a keyboard. Gamepad PCB allows you to retain true joystick movement.

you're shooting too high

[Anonymous No.2761842]

>>2761832
He isn't though. The only flaw in his plan is using a Pi for something that you needed a pretty high end desktop to do up until semi-recently.

Your college project is building something that has a thousand wikis online telling you how to do it. I'm sure your teacher at (insert shitty school here) will be impressed.

There appears to be a couple features not typically done with guides online. How about we help OP instead of shitting on him for having interests that pertain to the board.


OP, depending on where this thread goes I might give you my email and we can discuss this more civil-like. I like the idea of an online high-score database. Could be neat.

[Anonymous No.2761882]

>>2761874
you mean petrockblock.com? You're not going to be posting the highscores online without editing the roms. Unless you just want to create a screenshot shortcut for each game that knows where they should be uploaded.

You have no idea how mame works, do you?

give him your email. I'm sure he'll appreciate you googling for him. In order to extract a highscore from a rom you'll likely need a script that references it's saved data. Now that I've basically done OP's community or for profit college homework for him I'm off.

[Anonymous No.2761949]

Let me let you in on a little secret: The highscores aren't stored in the rom, dumb ass. Maybe learn what you're talking about before opening your mouth.

OP, it should be pretty easy to either a) write a way to read the highscore.dat file and upload it to the database automatically or b) cout out the highscore.dat file completely and have it just save directly to your online database.


You're probably better off looking elsewhere though since evidently everyone here wants to be ignorant assholes rather than contribute in any way shape or form.

This is honestly a much cooler project. Easier to take to class as well.

[Anonymous No.2761953]

>>2761949
I was speaking generally. Sorry if I didn't get specific enough or choose my words better for your tastes. I've actually provided him with more useful knowledge than you. I have been entertained how you've gotten triggered like a little tumblrina. Give him your email sperglord.

[Anonymous No.2761954]

>>2761949
So op's entire project is just him writing a script? He'll have to do no other work than that as it's already been done and documented online? Higher education standards are slipping.

>I WAS ONLY PRETENDING TO BE RETARDED!

You haven't done shit, actually. You didn't even know that Mame didn't somehow store information in Read Only Memory until I called you out for being retarded.

>>2761954
It's not as cut and dry as "writing a script", and again, from the sounds of it his project seems to involve features NOT well documented online.

Again, OP, you're better off asking other people for help because all you're going to get from /vr/ are idiots who's answer to everything is "HURR DURR GOOGLE IT CUZ I ALREADY DID AND NOW I'M GOING TO ACT LIKE I'M A GENIE ASS" "GO BACK TO /v//Reddit/9gag/etc" and "NOT RETRO"

[Anonymous No.2761970]

>>2761961
So extracting values from a .dat file using bash scripting isn't well documented online? Uploading values to a website or that websites database isn't well documented? You really are a sperglord. I'll leave you to your autism. Go on more about how I didn't use the term .dat file while the gist of everything I said was correct. I'm taking away 20 gbp from you. No more replies from me trollholio.

What do text books have to do with online score databases?

>>2761970
Forgot to mention: Here was no mention of highscores being saved to anything prior to my post other than one idiot who tried saying you would need to "hack the rom".

You honestly don't even need to download a textbook much of the time. Just google and actually know what you're looking for.

1. The same way you use other components of the project without running into legal trouble. Buy them.
2. Don't use a shitty platform. Remove your fedora and use a PC
3. Use arcade controllers to make arcade controllers.
