I finally got around to replacing the batteries on my old pokemon games. I was able to successfully replace the battery in my pokemon crystal. However, when I replaced my pokemon ruby battery, this is the screen I get. Anybody have any insight into what is wrong? Thank you!

Is there any way to repair my screen? I havent turn it on for almost like 15 years or so.. Is it possible to change the polarizer only? If yes.. how is the process? Is it difficult? Thanks before..

Recently I accidentally bought three Pokémon leaf green 😅 so I'm keeping one and I gave one away to one of my co-workers.

Hello! I just bought this beauty the other day! To be short, I really want to put a new backlit screen in this thing, mainly so I can play at night time, I intend to keep for very long time. My question, is do any electronic repair or video game stores do that type of service? Or, will I have to bite the bullet and suck it up and do it myself? I reallly dislike the idea of having to ship it away, but if that’s my only other option, please let me know. I did watch some YT videos, it doesn’t look crazy hard, however, this is a more rare device, and is minty. I really don’t wanna break or damage any of it. Any advice is appreciated. Thank you! 🙏

Just got a GBA SP but the shell is pretty battered so looking to get a new one. Does this need the IPS screen to fit properly or can I use the original screen?

I finally got them all

How did I do?

Need more gba red boxes

Been buying these exclusively from game stores and expos i attend, been working on it for 3 years, down to only needing 2 more to complete the set. The rest of my gba/gbc/gb collection and analogue pockets also included in the pic.

Hi.

I'm thinking of building a GBA SP from scratch.

However, I don't have the specific background knowledge to be sure if the components I'm considering will fit together.

I know there will be some soldering work but I can handle that.

I've googled a bit back and forth about which motherboard etc. would be best and have come up with the following parts:

Housing: Extremerate - IPS Ready (Black)

Handheldlegend.com

Motherboard: AGT-CPU-01

Aliexpress.com

Screen: Hispeedio V5 IPS

Handheldlegend.com

Battery: Funnyplaying 950Mah

Handheldlegend.com

Speaker: Funnyplaying

Handheldlegend.com

Charging: USB-C charging mod (which one?)

Handheldlegend.com

Handheldlegend.com

Buttons: Forest green

Handheldlegend.com

Screw hole cover: Black

Handheldlegend.com

Slider cover:

Handheldlegend.com

Soundcard?

I need to find a sound card, which one should I use?

Where can I find the internal screws for motherboard etc.?

Thanks in advance.

Just a demo for now, but I got one of my old PC games from 19 years ago playable on the GBA. You can download the game as it is now (second image with the slightly better snake head, text and better use of screen space) and play on a real GBA or emulated. First image with child hands shows the first concept of the game working, but I have tested the latest version as well.

Slide-o-Snake is a puzzle game which is probably best described as "turn based snake". You push a block into a hole and then your tail gets longer. The game is purposely dense about where the end trail and end of your tail is, it's up to you to remember where your snake body will move and offer space. This demo of "Easy Mode" goes up to 50 points, actually below what I would normally considered a complete game in it's other versions.

This is my first ARM assembly game, I normally develop for the Fairchild Channel F in assembly, I've dabbled a bit in 2600, NES and Amstrad Assembly but never got anything good enough to show off on those systems.

I've spent years trying to understand Channel F assembly before getting anything actually useful, I've been using ChibiAkumas website (also used to be known as learnassembly, shout-out to Keith and all the amazing work he does on that site, link here: https://www.chibiakumas.com/ ) to try and branch out into other systems. GBA with it's portability was always intended as it's fun to play my own games on real systems when I can.

I'm not going to lie, I did use ChatGPT for some of this. Most of it, how to understand how to assemble the code into a working ROM. I'm a video game programmer but I'm not great on anything else. Like a lot of systems, there is a knowledge threshold that will deter a lot of people from getting to something workable, I spent a whole day using chatGPT just to work out how to assemble the code to create a viable ROM. If I tried to work it out myself, given the documentation available I would have probably given up.

ChatGPT can do GBA ready code, but take it with a pinch of salt: it needs a lot of fixing and will likely not assemble without human involvement, thankfully because I'm versed in Assembly already, it is easy to understand where things go wrong for me. ChatGPT cannot be trusted to to do graphics for things like the GBA itself, all bitmaps used in the game are my own.

My plan is to finish up the other game modes, make the game a little prettier, and maybe do a general release. I have other 20 year old games I would love to port to the GBA, and some original ideas too.

One day I would love to do a 3D version of Slide-o-Snake for the N64 with 4 player support, one potential option is to make a link cable version of the GBA one and make a 2 player game (there is co-op and Vs mode in the original 2007 PC release).

The GBA demo version is free to play here:

If anyone has any questions, feel free to ask.

Going to probably mod the screen/battery but playing firered on the switch inspired me to get in on the OG action! Don’t know if I can go back to iPhone emulation now😭

Only purchased because it seemed legitimate from the 2 low quality photos (backside had GameStop sticker so it was working at some point lol). $14 for Castlevania seemed like a good deal... Until I opened the cartridge. Processed refund immediately, only problem is I'm stuck with this now. I don't know jack when it comes to soldering/swapping chips to new boards to save cartridges so my question is, is this at all salvageable? I've been wrong before so I thought I should ask those who are more knowledgeable than I. Thanks
