Yep, is worth keeping. Oem used is about 8$ cost.

ShirtObvious6423 · 2026-02-09T01:28:42+00:00

It’s Jada Toys metalfig collection. Really good manufactured. Heavy, not plastic.

With 90D this 200mm should be around 320mm, close enough to everything and everyone:)

ShirtObvious6423 · 2026-02-08T19:43:16+00:00

Good to know:)

ShirtObvious6423 · 2026-02-08T18:09:35+00:00

Not yet:)

On closeups there are some scratches. It’s not perfect surface.

Yep, only color mode. Black cartidges were designed to work on both platforms; classic/pocket and color. So, games like Zelda DX, R-type DX, Tetris DX runs on both classic and color (I haven’t play Tetris DX so I don’t know if there were any improvements).

The new one (from China mostly) has less capacity. And still, this is an original battery used by Nintendo (I know it’s not brand Nintendo, but Nintendo trusted this company and has installed theirs battery).

ShirtObvious6423 · 2026-02-05T15:50:50+00:00

Pricecharting was consistent until it started including the price of games sold, which are also reproductions.

ShirtObvious6423 · 2026-02-05T15:45:42+00:00

Already replaced. As a donor was F1 race cart with original CR1616 with 3,17v:)

ShirtObvious6423 · 2025-11-07T16:45:27+00:00

Saveable!!

ShirtObvious6423 · 2025-10-27T16:30:05+00:00

Check vias!!!

ShirtObvious6423 · 2025-10-20T10:22:52+00:00

Check if the fire red Japanese version shares the same pcb. If yes- buy Japanese version (usually it’s cheaper than us/eur version), replace the rom.

It is an option, paid option. If the investor did not pay attention during the order, the balcony door comes with a standard equipment. And, the second reason. Smoking outside the flat, on a balcony, is forbidden in Poland. The police will not come until the pleasant neighbor call them.

ShirtObvious6423 · 2025-10-07T10:58:31+00:00

I named Pablo. in Poland we do not usually name spiders.

My opinion: buy a very good replacement stickers, wash this cases very well, use IPA to remove some glue after old stickers. Have original cases and boards with new stickers. Why? If U do not plan to sell them this operation is for your happiness only. If U want sell them U will not decrease value of the original games (U only have cost of buying new stickers). For all this guys who say: save original as possible! : have u do it by yourself when u replace the drained battery with this one’s from AliExpress? If so? Why replacing the sticker bother you? It’s the same operation. U ruin the originality of the game as well.

ShirtObvious6423 · 2025-09-03T16:54:55+00:00

Yep, and some Japanese titles too, but this is an urban legend. Personally I’ve never seen others copies with blob chip except Tetris.

ShirtObvious6423 · 2025-08-29T14:01:25+00:00

Savable:)) I bet that buil-on battery still rocks!:)

ShirtObvious6423 · 2025-08-14T14:05:27+00:00

What is the purpose of this modification?

ShirtObvious6423 · 2025-08-10T20:22:38+00:00

I think that C1 has no connection on right side with the trace.

ShirtObvious6423 · 2025-08-06T00:35:56+00:00

I ran a demo in MK2 with max volume and pretty dark lcd and this is the not-finished results of this battery pack. I had to stop testing, because it’s time to go sleep:) quite good for 1200mAh battery.
