Famicom/NES dumps / Re: I'm new, but I have a dump : Thumps Up 240 in 1

"Nesmaker" on the chip manufacturer's page:
http://www.vrt.com.tw/download.htm

If it is an MMC3 ROM, then it should boot it, at least in theory. In practice, at least the LCD display will require extensive initialization to show any image, so you are better off keeping the 240-in-1's menu code, which does that for you, in place. The Nesmaker package's menu is for an earlier console and thus will not contain LCD initialization code, in particular since every LCD manufacturer and model type will require different initialization.

Do you know where I can find it?

And, what happen if I burn a single nes rom into the eeprom? will it boot it?

V.R.T. actually did provide such scripting functionality in its original VT02 development kit, though it used 6502 assembly code with macros rather than Python to do that, and if I remember correctly, a few C-written helper applications.

I've attached ROM with Abscondee replaced with Mario 1 as an example.

Hey, thank you for that, I removed the header I burnt it on the device and it works nicely, I think will take me a big effort to get up to speed with all that knowledge, I'm an embedded programmer ,so , nothing new there but there is lot of legacy information...too bad...I was already dreaming about a python script that generate menu and roms automatically....

You never replied to me originally...
I have no idea what you are talking about. I think I was quite clear when I wrote "I will gladly continue the project, though I will probably choose more conventional folder names.", and you were quite clear when you replied "That would be great if you could, but only if you're up for it." I am not aware of any unanswered communication.

(also one more sidenote for NewRisingSun - the Nintendulator you posted won't run the majority of pnp VT03/09 extracted roms. is there a reason for that?)
Yes, because ever since I had originally sent them to you, I had to add additional NES 2.0 header fields specifically denoting what type of VTxx hardware the games ran on, and without those header fields, the emulator now runs them as regular Famicom. So they all have to be re-headered, a process that I have already finished on my end. This change became necessary when VT32 and VT369 ROMs were discovered, and there was no way I could continue just auto-detecting the VT chip type being used.

We had earlier agreed that I was going to release the next Project Plug and Play update. I have already started working on it.
You never replied to me originally...I meant more that we would do a collaboration effort, not that you would take over the entire project. Since you never got back to me I figured you changed your mind... (not trying to sound rude here, i'm just confused)

So...is the content encrypted ? I wanted to make a custom rom with official NES games in it , instead of bootleg ones, I noticed that the roms are saved in "banks" , I tried to replace one with Super Mario Bros. 3 but that did't work (I guess the mapper is unsupported?) perhaps with the emulator now I can try the edits before burning the eeprom :)
To put game inside a multicart slot, you have to match the game + graphics data in the correct place, with the correct size. Mario 3 wouldn't work because its a 384K game, none of which are inside the 240-in-1; Mario 1 would, as many games on the console are 40K. They also can only be mapper 0 roms.

to find the gamedata, take the project plug 'n play rom for the specific title, and search for the first few lines of code in FCEUX hex editor. then replace the code with the game you want in its place. do the same process for graphic data. (does that make sense at all? i'm terrible at explaining these things)

Replacing the existing games in that plug and play requires extensive knowledge about the OneBus banking registers, and if the games are to be integrated into the existing menu, how the menu uses them. If the subject interests you, begin by reading the relevant articles on nesdev (1) (2). Super Mario Brothers 3 uses the MMC3 ASIC, to which the OneBus chips are backwards-compatible, provided you correctly set up the PRG and CHR masks and offsets. The game however expects an additional 8 KiB of WRAM at $6000-$7FFF, and I am not sure whether that is included on your PCB.

You will not have to scramble the instruction opcodes in the game's ROM, because the menu disables scrambling before proceeding to launch the selected game.

Sadly I haven't got any other device like this but if I get one in my hand I would be happy to dump it.
If you are looking for a challenge: My Arcade DGUN-2573 Gamer V needs to be redumped because the current ROM image is corrupt. Davidstech has said that it uses a different kind of flash ROM chip that is more difficult to dump.

Thank you for the fixes NewRisingSun!

Edit: Nevermind, I re-read your answer, I guess , I either swap the  opcodes in the rom I want to paste in or I disable the scrambling in the eeprom ? (if is even possible?)

And no, it uses a VT369 but  merely does not make use of any of its advanced features beyond the opcode scrambling, the 8 KiB of CPU RAM (NES has 2), and the 15-bit RGB palette.
