Finally the big systems, one MV-1T, two MV-1FS, and one MV-1F, honestly these don't look good but we got to clean them up and see if we get anything out of them.

This is how the boards look after removing the batteries, pretty disgusting:

Boards cleaned up, much better:

There's some moderate amount of corrosion on these, some IC legs look a bit corroded, 3rd system I can see it's missing a capacitor near the center (labelled 10 µF), the 4th one spots a repair.

Testing goes as follows:
-Stuck in green screen
-Fully working
-Stuck in click of death
-Fully working

Overall not bad! 2 out of 4 worked, I'll reassemble them and try to fix obvious problems like the missing capacitor and see how it goes.

(cont.)
The MV-1B's cleaned up really well, first system spots a small repair and resoldered IC (labeled MASK1), some systems present small corrosion spots, nothing too bad.

Testing goes as follows (from left to right, top to bottom):
-Fully working
-Fully working
-Black screen
-Black Screen
-Working, some buttons don't work but JAMMA connector is really dirty, I expect it to be fully working after cleaning the connector

3 out of 5, not bad so far!

Sorry for not updating earlier, I did went though all of them last Thursday and Friday, I'm going to go quicker this time with less pictures overall.

These were the five MV-1B's in the lot:

Forgot to take picture of the boards before cleaning but they were extremely dirty, here they are after a good clean up with the power washer:

MV-1Cs are ready to be tested.

Board 1 - Looks good, it had a blown fuse so I replaced it
Result: No image, CPU did get a bit hot, found a cap that is shorted near the CPU so most likely shorted CPU

Board 2 - Looks good
Result: Fully working

Board 3 - Looks alright, a little bit of corrosion near the NEO-YSA2
Result: It booted, wouldn't take carts or display sprites with garbage, so I gave the cart slot a good clean and finally it worked correctly, another fully working system

Board 4 - Looks good apart from some small amount of corrosion in the underside of the cart slot
Result: Fully working

Board 5 - A little corrosion near the NEO-YSA2, blown fuse so I replaced it.
Result: Fully working

These were much better, tomorrow I'll try to clean at least the MV-1B's but I'll try to get them all.

Next up are the MV1C's, the lot had 4 of them but I added a 5th one that was sold to me recently as non-working, so here they are:

Boards ready to be cleaned:

Boards cleaned up really good:

I'll probably test them later tonight if I'm sure they've fully dried, these are looking good so I'm hopeful!

So boards pretty much got cooked under the sun so they're ready to be tested.

Board 1, MV-1ACHX - This one has heavy corrosion and some traces seem gone already, don't expect to get anything out of it.

Result: Green screen

Board 2, MV-1FZS - Looks decent, might get lucky with this one

Result: No audio but works

Board 3, MV-1A - Very light corrosion in some spots 

Result: Wouldn't boot, click of death or solid color

Board 4, MV-1FZ - Some ICs legs don't look good

Result: Weird audio issue, as if it were too high, but it works.

Board 5, MV-1A - Some corrosion spots in the board, there's a weird bloated spot in the BIOS chip

Result: Click of death, even after swapping the BIOS chip, seems that the corrosion did get some traces.

Overall a little underwhelming, only a couple of them are working with audio issues, these were the ugliest ones of the lot so not surprised with the result. Next I'll do the MV-1C's, those tend to do well so let's see how it goes.
 

Couldn't clean any yesterday so today I began with these MV-1A/1ACHX/1FZS that seemed the dirtiest of them all:

Removed batteries from boards to get them ready:

Power washer:

Here they are cleaned up and getting dry under the sun (it's scorching outside), they already look pretty good to me, a few have some corrosion but doesn't look that bad, I didn't separate the boards from the cartridge slot but I'll do before re-assembly to make sure everything is dry and looks good, also I have to clean the JAMMA connectors:

That's it for now, I'll test them tonight and report back how it went.

EDIT: Decided to separate the boards from the cartridge slot, should've done it before cleaning but no worries, I'll manually clean these connectors:

Today I unpacked a lot of junk MVS systems that I bought for scrap price, in total I believe it's 18 systems, 3 MVS games, an unknown bootleg game & a NES connector somehow got thrown in, along with a wrench, everything is super dirty:

I'll try to clean them up the following days and report any progress as I go through them, for now I might hook the bootleg game as it isn't that dirty on the first place just to satisfy my curiosity. Wish me luck!

This one is intense, amazing in a very weird way.

Globalization has made purchasing anything from overseas easier than ever so demand is adding up, it's just a fact that some stuff will leave a certain country indefinitely but in return some stuff previously unavailable is getting into the country as well. Japan are obviously the prime example of this, huge videogame culture so lots of consoles and games have been constantly consumed by the Japanese, severely reduce living space in urban areas meant old video games were quickly regarded as junk taking space so an overwhelming amount of games are constantly getting discarded, for westerners the Japanese releases factor in a lot of eye candy and everything seem really cheap, even for non-collectors I can absolutely imagine the scenario were a tourist visiting Japan comes across a game store and picks up a few of his favorite games as a souvenir, so naturally some stores started to focus on selling overseas since there's demand.

Song: Ablaze by School of Seven Bells

Album: Siamese Dream by Smashing Pumpkins

Artist: The Jesus and Mary Chain

Genere: Shoegaze

No surprises regarding the outcome lol, solid top 4 for sure, out of the 64 songs I only had 5 of them in my playlist, most had an early exit but it's nice to see 2 of them against each other for 1st, I voted Take on Me even though I really like both songs.

@RH try calling eBay and see if they can see exactly how and when the item condition got changed from Used to For Parts, I suspect the seller couldn't have done it though a regular item update but maybe he could've called customer service and have them update it, looks like it was some sort of unintentional bait and switch where eBay is to blame.

Yo were sold the item listed as Used, so it should've been fully functional per eBay's item condition guidelines:
 

https://www.ebay.com/help/selling/listings/creating-managing-listings/item-conditions-category?id=4765#section4

• Used: The item was previously used. The item may have some signs of cosmetic wear, but it is fully operational and functions as intended. This item may be a floor model or store return that was used. See the seller's listing for full details and a description of any imperfections.
• For parts or not working: The item does not function as intended and is not fully operational. This includes items that are defective in ways that render them difficult to use, items that require service or repair, or items missing essential components. See the seller's listing for full details.

It comes down to what exactly the seller entered in the Condition field, acceptable and above the item is expected to be in working condition even if sold as-is, if listed as not working/for parts then this is an expected outcome, I see the seller (intentionally or unintentionally) left some crucial info out of the description but if it was correctly listed as not working/for parts then that pretty much settles it.

Got back into gaming because of the PSP, basically treated it as a portable emulation box, the small screen never bothered me, I owned a Gameboy as a kid so maybe that's why the small screen never bothered me, I really enjoyed the PSP for years and played many games there (mostly NES and PS1, but also some GBA, SNES and Turbografx). Regarding Gameboy my experience was good but I mostly sticked to good GB exclusive games like Super Mario Land 1 & 2, TLOZ Link's Awakening, Final Fantasy Legend 2 & 3, always avoided watered down ports.

@imthomas have you seen examples for other consoles? You can just look at the staples in Playstation games since the case is transparent, the same goes for Sega Saturn and Dreamcast games.

MIA since week one.

LOL I've been playing Xenogears, I'm on Disc 2 and the truth is that I've been slacking on it but it's time to wrap it up. Also did got myself a Vita and really happy about it.

Some urban exploring youtube channels show some creepy places, this one for example is called Abandoned Central:

Shadowrun for the SNES is great, I'd recommend that one, there's another game for the Genesis that is also good but I haven't played it.
