Home built wideboy advance
« on: June 01, 2013, 12:23:13 pm »
It's all done except for relocating the cart slot, wiring in controls and obviously building a case for this thing.










Wideboy + home built devcart + colorized gameboy romhacks ftw!



Once I get this thing more built I can have direct captured gameplay footage of gb, gbc, and gba (oh wait I don't have a gba flashcart yet) romhacks running from the real hardware.  It's all hardwired together and glued firmly so nothing will break.  Uses a single ac adapter.

Thanks to bacteria for posting the hard wiring guide-o.

Thanks to the taiwanese company that made this tv converter thing.

The video connections were all wired wrong by default and the s-video output circuit needed tweaking but i fixed it all and completely got rid of all the video distortion.

Man Drakon you make some cool sh*t. but...this seems mighty pointless in fact of the GameCube's GameBoy Player or the upcoming Retorn5 and evident GB/GBC/GBA adapter for SNES by RetroBit. A lot of work to do something that GameCube owners have been doing for a decade now.

Practically speaking I am going to have to agree with Satoshi_Matrix but that is not necessarily what hacking is about so I can go in for it.

"home built devcart"

Colour me interested if this is for the GBA, I have seen http://www.ziegler.desaign.de/GBA/gba.htm#homebrew%20flash%20cart before but nobody has really tried anything for some time and whenever I think about it I think about fiddling with bankswitching and other nonsense and decide "maybe later" (basic flashcart -- easy enough, commercial grade or better -- considerably less so).

I do it for fun.  This way I don't need a stupid boot cd to fire it up.  Also buying this stuff is cheaper than buying a gamecube + gb player.

Wouldn't playing GB or GBC hacks on a GBA require the use of Goomba?  If you want the real thing, I hear the "USB 64M Smart Card" is the way to go.

Hardly.  The worst thing that could happen would be that the GBA would get fried. We are not talking about high voltages here.

The original GBA and GBA SP support GB/GBC. It is only the micro and DS that don't support them.

Yup so with this baby I get to enjoy gba, gbc and original gb games on my tv in perfect looking s-video.

Jorpho is right nothing is unsafe if you know how to place things so nothing shorts.  Notice I have it sitting on a plastic lid to prevent shorts.  Guess what consoles are, pcbs housed in plastic cases.  Jorpho is again right about low voltages inside of it, what do you think that giant ac brick does?  It brings the voltage down to a teeny level that could barely power a bug zapper.  This isn't done I'm building a case for it with a straight wired controller port.  This's just the difficult / annoying part of the work out of the way, the rest is fairly safe and straightforward.

It just seems a little pointless now, since in addition to the GameBoy Player, RetroBit recently announced a Super NES adapter for GB/GBC/GBA games, similar to what the Super GameBoy is but more advanced. It will even come with it's own link cable ports for mulitplayer.



I have no shortage of ways to play my GameBoy collection, but I'm excited for this myself. Still, it doesn't take away that your hack is very cool though. Just kinda....ten years too late?

I'm NOT trying to make something for people to buy.  I wanted something that's the real hardware and works nicely without the need for a boot cd.  That's what this is.  This is for dev-work and romhack fun, personal use.  Why do you treat every mod I make like it's something I want to sell?  I'm not trying to compete with whatever else is out there.

I completely agree. Not all endeavors must be motivated by utility or an original purpose that no one else has achieved before; personal gain and motivation, the experience of achieving a mod like this, is more than enough.

I wonder why so many people seem to think something isn't worthwhile simply because there have been previous alternatives... It seems a pretty narrow and provincial way of thinking  :-\

More power to you!  Sometimes making stuff for yourself is more rewarding than making something to sell.  Don't get discouraged by any the comments that you don't like.  Keep up the good work!  Wish I had that kind of skill to build stuff like this.  :)

That is true, but you cannot boot into "GB/GBC mode" on a GBA or GBA SP with a standard GBA flashcart.  That's why Goomba is needed – to run GB/GBC games in GBA mode.

In theory, you can use an ancient Flash2Advance cart (the ones that ran off a parallel port) and something called a "GB Bridge".  I've also heard suggestions that you can force GB/GBC mode just by sticking a piece of paper on the right pin in the cartridge port.

Other people told me the GBA/GBC mode is toggled by a tiny switch that gets physically pushed by the weight of the pins on the appropriate cart.
That would explain why I've heard of worn consoles being unable to boot one or the other.
(wish I could remember the exact details)

Instead fo using an ancient flashcart for gb / gbc stuff I built myself a gb / gbc cart that takes eproms and eprom pinout flash chips:





With standard eproms this thing goes up to 8mbit games.  I've since upgraded it (no pictures) by adding address lines to attach chips that go all the way up to 64mbit.

The gb / gbc switch is pushed by the cart shell.  GBA carts have grooves near the pin connector so they don't hit the switch.  It's a stupid design, they should have just made a bios that scans for gba code.

Given it also drops the voltage from 5v of the GB/GBC to 3.3V of the GBA and the annoyance of doing probes on 2001 vintage hardware (ignoring that the GBA was not exactly cutting edge even then) vs a simple switch I would not call bad design just yet.

I have exactly the flashcard you're talking about and this does NOT work (I tried). I'm also glad it didn't destroy the flashcart, considering the GBA becomes 5V when you force it in to GBC mode while the flashcard has been designed to be powered by 3V.

Voltage difference I wasn't aware of.

Now that's pretty nifty!  Did you make it from scratch?  I guess you have to burn a fresh eprom each time you want to play a different game.
