AladdinXT Conversion for Lcd

Recommended Posts

Hi all,

As a fun educational exercise to wanted to replace the CPLD logic on the cheap AladdinXT 4032 Original Xbox modchip and convert it to a basic LCD driver, consequently it looses the ability to load a custom bios. I consider this to be something like the old X-addons generic LCD-display mods (but a fair bit simpler)

The Lattice LC4032V CPLD on the cheap Alladin modchips is extremely limited, so this is a hacky bare minimum to reduce macro-cell usage to fit onto the CPLD. Therefore it can't really support any extra functionality over the bare minimum.

It doesn't support backlight control (just full brightness always)

It has some very basic contrast PWM control through the dashboard settings.

Anyway just wanted to share what I came up with

Ideally, you could design a small PCB (and maybe use a larger CPLD) to improve the installation. that is something I may do in the future :D

This project looks very interesting but sadly I don't even understand half of what you are talking about.

I read the instructions and step 2 & 3 are in perfect chinese for me:

1. JTAG PROGRAMMER: Model ? Picture ? Where can I buy it: Amazon ? Aliexpress ? Link ?

2. APPLY 3.3V POWER TO THE ALADDIN PCB: From where: Motherboard ? DVD Drive ? Xbox Power Supply ? Picture ?

3. PROGRAM CPLD: What's this ?

4. UrJTAG PROGRAM: Will it work on Windows 7 Home Premium 64bits or I have to go back to Windows XP ? How to use this program ? I only found this video from 2015:

... do I have to do something different / add another step ?

5. COMPATIBLE PROGRAMMING CABLE: Picture ? Where can I buy it: Amazon ? Aliexpress ? Link ?

6. The light gray cable you are using is 30AWG ?  28AWG ? 

Feel free to be as detailed as possible.

I apologize for all the questions. Better be safe than sorry.

Thanks  :)

I got 3.3v from a bench supply but you can get it from the xbox if needed. Up to the hobbyist. 

28awg wire will do.

What is a CPLD? Did you try google? https://en.m.wikipedia.org/wiki/Complex_programmable_logic_device

See this too. It tells you the required operating system, supported cables etc. http://urjtag.org/book/index.html

Try installing the libusb-win32 v1.2.6.0 drivers using the Zadig_wdi installer

https://sourceforge.net/projects/libusb-win32/files/Zadig_libwdi/

I cannot test if this works since I have no USB JTAG cable to try.

Update: I do see a 2.4 release of this installer available at the dev's web site:

https://zadig.akeo.ie/

Usage guide:

Thanks to help! Witch https://zadig.akeo.ie/   libusb0.dll is ok!

To which directory should I upload the ALADDINLCD.SVF file?

Placing the svf file in the same directory as jtag.exe will be the easiest. Then you can use the command as shown in the github instructions

Now the matter of the chip?
I have old chips from 2005. They're ok?

My code was designed with the cheap clones in mind you pick up from eBay nowadays

I dont know if they will work with my code as the pins being used could be different. Id recommend sticking with the clones.

      So, I'm an old man and I can't remember how I flashed this XBox years ago. I have an Aladdin XT Plus2 with Evox +3935 and M8plus_16 fan 40.06 (not sure what size bios that is). I wrote a 2TB image to a drive and get an error telling me to upgrade to LBA48 ver 2. Can someone point me in the right direction. I do have FTP access to the box.

      hey all,
        Building a cocktail arcade cabinet, which requires the display to be mounted vertically instead of the typical horizontal orientation.  The TV display we are using doesn't have the ability to do it within its menu.  I've seen an option to do so on non Xbox arcade cabinets (and it actually flipped 180degrees for 2 player games as well) , i was wondering if anyone knew how to do it with a modded xbox, either natively within UnleashX or XBMC-emustation or XBMC4Gamers....or another way.  CoinOps has limited capability to do so with certain games, but it also inverts controls when doing so.  Any help or guidance you have would be greatly appreciated.  Thanks!
