Famicom/NES dumps / Successful Sup 400-in-1 complete dump? Runs in EmuVT 1.36
« on: January 26, 2023, 10:11:47 AM »
Hello,

I had recently dumped the Sup 400-in-1 handheld ROM from the NOR flash and it runs in the EmuVT 1.36, using the combination of MCP23017s and a Raspberry Pi. The process is pretty slow and it took a whole day to do it. This carrier board is extracted using a ChipQuik and then inserted into a SOP to DIP adapter.

The schematic for the ROM board is obtained from somewhere (see attachments) that has the possibly correct address lines at the A22 and A23. The other schematic for the ROM board has a /WE instead of the A22.

Most of the games run fine except some of them. The ones that don't run well often has empty screen and glitching up. I'm not sure if the dumping process has not been good in between.

Curiously, I examined some parts of the program code through its debugger. I'm not sure where are the LCD initialization routines during the startup. I checked through the VT-03, VT-16, VT-18 and even the VT-168 datasheets for the TFT-specific registers but couldn't find any hint on these.

I'm not sure if this is another version of VT that I've never heard of, or I may be looking at a wrong place. The romdump is attached - maybe the BGC experts can have a look inside? :)

There are also attempts of dumping by some people in another forum too: https://4pda.to/forum/index.php?showtopic=979648&st=480, however the romdump link is no longer available.

Famicom/NES dumps / Sup 400-in-1 handheld dump
« on: November 17, 2020, 10:44:31 AM »
Hello there,

I just happened to extract the COB ROM and tried to dump the contents using the Raspberry Pi and a couple of MCP23017s. [Story here: https://hackaday.io/project/175322-dissecting-a-hand-held-noac-console]

I tried running this on the Nintendulator which is modified for VT-series NOAC but couldn't run. I'm suspecting this one is a possible variant of the VT series where the reset vector is entirely different.

Inside the dump I could see sprite sheets as usual with some data in between, but I couldn't find a lot of references on the 400-in-1 menu text. It could be possibly encrypted or the dump is incomplete.

The dump is attached here for the reference.

Famicom/NES / MP5 "Gameplayer"
« on: March 11, 2015, 11:05:26 AM »
Hey there,

Yesterday, got this thing, bought it cheap from a local retailer online.

Went and unwrapped it and found that it's preloaded with a number of GBA games. Not in my era, but some of them were OK to me when I tested them.

So I added the usual "Battle City", "road fighter" and some other classic games - they worked pretty well.

However, I can't get Gameboy B&W games to work - they won't even run. Said "invalid format". I've checked around the net, but found nothing much about people playing those on that player.

Here's that pic attached.

Classic games without the mapper run pretty well, the one with certain mappers suffer from stuttering sounds and incomplete music, like the "Barbie" for the NES.

Pirate Talk / What made you got interested in bootleg old-gen console games?
« on: March 03, 2015, 11:31:09 AM »
Hey there guys and girls,

I'm sure most of you are in the USA or probably Europe - I could guess that bootlegs there are even rarer.

How did you come into contact with this? From some episodes of AVGN and some other comedy channels/reviews, maybe you might have that NES cart with a very strange color.

I'm in SE Asia, so we don't see those tall grey cartridges. Believe me, we never seen ANY of these carts before. We have the Famiclones there, because it's all we got. Owning an SNES or a Genesis was out of the question at that time as we were not having the moolah yet.

The only console I got when I was a kid was a Micro-Genius one with a 20-in-1 multicart. It was in 1992.

And also, I could tell you that in 1995-1999 those stalls selling those carts are almost everywhere. These carts with different colors are adorned on the counter. Whatever-in-1, bootleg games, and some original copies of Mortal Kombat III were there. No Nintendo 64, 'cause people there are obsessed with PS1.

I was exposed to all these things that I've become very shocked to hear that there was an actual "original" Famicom cart or NES cart elsewhere. All my life me and my friends were having played those bootlegs on the console.

One of my friends played a lot of games. That including a mountain of those small Famicom carts. One of the games was a beat-em-up. I saw the fighters' names "Moon" and "Cliff". Dunno what was the game at all, I believe it's another bootleg too.

I'm sure you have some nice stories to share about them. :)

2000-present / Weird Famicom handhelds - worth buying?
« on: March 01, 2015, 11:28:51 AM »
Hey there,

I'm new here, so don't get too rough on me. :)

So here's the story: I've seen weird Famicom handhelds being sold in toy stores. One of them which is the PVP-station, which contains a ridiculous amount of games (99999-in-1) and these few games looped. The game cart inside is tiny and flimsy - I wish I can see what is inside.

Then I'm seeing this:



8-bit retro RS-1

At least they have like 100 games instead of many 9s. I've checked the list, they have my all time fave Battle City, Dig-Dug, Road Fighter and Super Mario.

Too bad I can't swap games or write homebrew inside. I don't have a teardown picture, but all I can suspect is, there's a huge NAND flash inside. Maybe I can desolder it and reprogram it. I don't know - I'm guessing, which means I can be very wrong.

And lastly, the MP5 player:



Mp5 player in Ebay

Now this one is weirder. I've read elsewhere that this thing uses a fast processor and it can emulate NES, SNES and GB games. All you can do is to load up the games into the SD card and run them. Could I write my own homebrew games and load it inside the system?

Would like to hear your opinions about these weird toys. :)
