Arcade1Up Hacking

Thanks to some heavy coin-pusher usage at a local amusement center, this unit was 'won' and dragged home on the train. Pretty funny watching everyone watching me carrying a box'o'arcade machine on public transport!

In no time the machine was upright and SF2 was being played. All very nostalgic from both childhood and ... exactly 10 years and 10 days ago when I built MAME controllers from MS Keyboards.

The unit came with 3 versions of SF2, but it was never my intention to keep it stock. The unit itself would provide a perfect base to build a fully-fledged arcade machine with all the games of my childhood!

The Base Hardware

The unit has an AllWinner ARM SOC built into a case mounted behind the screen. It's a tiny board that wont be easy to flash or extend. This actually means that there's a ridiculous amount of free space in the bottom of the unit as the actual electronics are tiny.

The ARM board would be difficult to re-flash and would also be limited with storage, so the decision was quickly made to replace the guts. Fortunately I could still use the screen and controls.

The New Hardware and Software

To use the screen, I had to purchase a controller board. It seems that the Arcade1Up guys have used a screen that's popular in other actual LCD monitors and therefore the boards are easy to come by. I found one on eBay... just search for LCD Controller Board For HSD190MEN4 M170EN06 17 inch D2K4. Pretty cryptic, but it's the model of the LCD.

With this unit swapped in, I now had VGA/HDMI/DVI access to the LCD! From here, I grabbed the nearest motherboard which happened to be an AMD Sempron X2 with 16GB RAM. I initially tried to use a GTX970 as well, but the compatibility with retro Linux distros wasn't up to scratch and therefore just stuck with the onboard video.

The controllers were wired in with USB Joystick Interfaces from Jaycar. They both were really plug-and-play and it meant I just had to unplug the controllers from the current distribution board and plug them into this one.

Choosing an OS can be difficult as there are a few great options: Lakka and Recalbox. I can't remember why I didn't enjoy Recalbox.

Slow Boot

I had initially installed a spare 1TB SSD, but found out quickly that it was unhealthy. I hadn't guessed it was the issue to start with, until I enabled SSH and reviewed dmesg.

You'll notice it's all milliseconds until it tries to bring the ATA up. Then the following occurs with a 30s timeout:

ata5: lost interrupt (Status 0x58)

Eek. Seems my SSD is faulty! I switched to another drive and that solved the issue seeing the machine boot in a few seconds. It turns out that other humans have added kernel boot params to get around the issues with the old drive, but I really didn't need all that space!

Controller mapping?

Here I was expecting a standard for RetroArch, but it seems everyone has their own ideas. And you know what?, I'm cool with that... It allows me to customise everything on my side also... just means a bit more configuration-work. I started with SF2 on MAME2010 engine (assuming the latest was the best?) and quickly found out that P2's keys weren't fully mapped. 1,2,3 and 5 were, but 4 and 6 were missing! No varied kicking in SF2! I hit TAB to check out the configuration inside MAME:

Ok, so it's BAY along the top buttons and XLR along the bottom. This all matched to the Lakka config, but the buttons still just wouldn't work. A quick google saw it to be an un-fixed issue. Switching back to mame2003 fixed it! But then introduced another issue: You need to switch the default controller to digital and make sure the input is simultaneous (keyboard + retropad):

The above shot shows how to get to the config... press F1 when in-game and scroll down to Options. It's a bit daunting, but works fine for all games after the settings are adjusted.

Extra Buttons Required

So, the standard machine has 6 buttons, a joystick and a 'start' button per player. This is great for Street Fighter on free-play, but not so good for a machine with multiple games. To get around this, I bought some arcade buttons from Jaycar and designed+printed a piece of plastic to house them off the side of the machine. I also had to but longer screws as the provided four only bit in about 2mm with the standard controller face.

The goal was an ATX power power switch (using the LED inside to act as the power LED), a coin button for each player and finally a reset-to-menu button. The final button's LED was also wired into the HDD activity LED.

This provided all the buttons required to play everything in the system. The Power button also nicely worked to shutdown the system, as a single press whilst the machine was running would cause a soft power-down!

Playlists

Lakka defines a playlist as a group of ROMs linked to an engine, under an icon in the main menu. It tried to guess all this by itself when you do a full directory scan and it's gotten it wrong every time I've used it. Your best bet is to dump all your ROMs over in one hit, run the scan directory, then jump back on the network share and merge the lists.

You can see above that I had Final Burn up there somehow as well? All the ROMs I introduced were just for MAME, so I have no idea how it CRC-matched them to another system. Anyway, the merging is simple as the file-format is JSON. Once done, delete the old files and restart retro-arch.

Finally, don't expect everything to work...

Just dragging and dropping ROMs from your downloads to the game machine, scanning and running will work with limited success. When you're acquiring things, make sure you check the hierarchy on some sites as they show you that, more-often-than-not, parent ROMs are required. Some ROMs are just old dumps with internal files missing in the ZIPs, so get ready to merge and re-test.

One note with Lakka is that it doesn't easily tell you what the issue is. Usually you'll just get a "Failed to load xXX". When this happens, SSH into the machine and type the following:
