Hi guys,

 

Back with fellow Atariage member NeoTurboManic. Let's listen to what he has to say about the comparison of World Heros for the SNES and Genesis again shall we? :)

 

From the description,

"This is a re-post of the same comparison video I did a while back. I added an annotation regarding the controls for the Sega Genesis port."

Awesome footage of all three versions, I never knew they had a Genesis version. The second one I used to play at Pizza Hut in Atlanta all the time! The deathmatch levels are so great!

Glad that that video help you know that the Genesis version of World Heroes exist. :thumbsup: It's nice to have in your collection.

 

Amazing Field...I use to play Neo-Geo plenty of times in Pizza Hut as well. I always wondered if Pizza Hut and SNK had an agreement to have them in their restaurants in the 1990's or at least with local distributors to have them. I use to play World Heroes 2 and Samurai Shodown 2 in the restaurant while enjoying a "thin 'n crispy" when the unit was occupied! :-D

 

 

 

I use to play them on the 2 slot goldie unit. Did that Pizza Hut had this unit Field?

fdurso224 was kind enough to point me towards a broken AES to add to my ever expanding hardware. He thought it would be a good idea for me to share the repairs and the story with everyone.

 

The unit itself is in pretty good shape. It came from a Japanese seller with missing sprites but showing a blue diagnostic screen. Upon receiving it I was able to confirm that it was in the exact condition the seller pointed out.

 

Whenever I have systems like this come in for repair I like to see the issue and then open the console up and see if it has ever been tampered with. In this case it had not ever been opened before and did not show any obvious signs of damage. So no blown caps, obviously damaged traces or broken components.

 

The first step after board inspection is to do the "flex" test. Basically for those not aware, this is literally going around the board while it is powered on and just pressing on chips and tracks of traces. This will help point out broken solder joints and broken traces. In this case, again there was nothing obvious.

 

The next step is to remove the BIOS chip and install a socket. The reason for this is to be able to swap BIOS whenever needed and in this case to install a Diagnostic BIOS. The Diagnostic BIOS returned no errors, so next up was to run the Universe BIOS tests. Again no issues. I didn't expect these to show anything, but it's still a good test.

 

So the next part is where things become interesting. Since this was to be my personal console, I decided to pull all of the RAM and buffer chips that we have seen fail frequently and socket these as well. While doing this, I did find a few corroded traces which I installed jumper wires for, but this did not correct the issue. I also installed known good chips to verify that the issues were not with any of these chips.

 

At this point ruling out the more common chips, it was time to focus on the custom chips. The Neo-B1 handles the sprite layers as sent from the cart. Before checking traces, I went ahead and reflowed the Neo-B1. This doesn't take very long and will help me if I end up having to remove the chip later. The reflow did not fix the issue either. However it did help enable me to drive the sprite layers as I saw fit. This showed me that I could alter the errors being seen on screen. From this point I had to follow traces from the GAD0-3 and GBD0-3 pins on the cart connector to the Neo-B1.

 

Now, this is not the only way to test these, but I do not have a scope in my shop right now and I had to buy a new logic probe which will be here tomorrow, so I was doing this solely with a multimeter. After testing each pin to see if I was getting continuity from the cart slot to the Neo-B1 I found the GBD3, the last one of course, did not have continuity. From this point it was a matter of following the trace to determine where the break was. Many people would just run a new wire from the cart slot to the Neo-B1 and that's ok. However my goal was to keep this as OEM in appearance as possible while also keeping any jumper wires as short as possible and crossing as few components as possible, to minimize interference.

 

After following the trace I found the break was actually underneath the Neo-B1 itself. How this broke, I have no idea. Despite having the equipment to remove the Neo-B1 and repair the trace, I made the decision to use a jumper wire instead of taking the risk of removing the chip and potentially causing additional damage, keep in mind the Neo-B1 is a QFP160 package.

 

After adding the jumper wire, everything was perfect. At this point, the console is good but I am going to replace all of the capacitors since they are TK brand. I also cut the traces running under the crystal to minimize jailbars and I will be installing a new RGB amplifier soon.

 

I know this was a long read, but fdurso224 and I discussed putting the entire story out there for you all to read. I do have a few more broken NeoGeo consoles coming my way for repairs, so if you would like to see or hear more about repairs let me know and/or check out my website. The pictures are large because I take high quality pictures of everything I work on. Also I need to make better labels for UniBios, but please note that the UniBios I am using is authentic. I have permission from Razoola to purchase and burn my own UniBios chips for installations. I cannot sell the chips outright without an install however.
