The light will pull too much power, and this is what prevents the system from booting, and gives you that flickering. However, you should not connect to it directly.

The voltage out of here is constant (the regulator does the job of converting your batteries' changing V into constant V for the system) so your light will not change in brightness. This point is the post-regulator 5v output which feeds the GB. Instead, you SHOULD use the point you're told not to, the top one of the 4 on the left. So, with fresh batteries your light will be bright, and the light will gradually decrease along with the batteries' juice. Why is this a problem? Because, as the batteries drain, your light will get dimmer and dimmer. The top point on the right is the V input, which comes straight from the batteries. In their video you're told to solder the + to the top pin of the 3 on the right, to avoid the system not booting or flickering. Here's another point where I disagree with the official HHL instructions. So I've been searching online for days trying to figure out what the issue is, and I think I've finally found it. I got some non-rechargeable 1.5V batteries to try, and the brightness level with them is very near what it is with direct DC input, but it does dim over time anyways and it is inconvenient to be constantly buying new batteries. To answer the other question in your first post, yes the USB 64m smart card does use up more power. also if you check out the pictures, there's a pretty clear voltage increase with DC vs battery power. i couldn't speak to whether KB is brighter than HHL or not but most people seem to think they are roughly the same. it also shows not to use the KB configuration like i did.

you could always install a 1k trimpot instead of the resistor like i was planning to do, which allows you to adjust the brightness. It will be brighter without the resistor according to HHL in the comments on this page, they say voltage is good up to 6V, but it may be too bright for you.

Any idea why that is? Does the flash cart suck up more power than a "legit" cart? The HHL website says I can use the configuration with the red wire at the top of the four points, but I will need a 100 ohm resistor, correct? Do you think doing this will increase the brightness of my screen?Īs a side note, I tried using the GB USB 64M smart card with it, and it makes the screen a lot dimmer than it is with a normal grey GB cart like Tetris.

On the bottom right of the PC board, I connected the black wire to the bottom of the four points and then the red wire to the top of the three points, as was shown on the HHL website:īut I found a post on reddit that seems to suggest that connecting the red wire to the top of the four points will make the screen brighter: But just running off of eneloop batteries, the screen is a bit dim.

I bought a power adapter so I could connect the Game Boy directly to power through a wall outlet, and when I do that I found the screen brightens up and looks really nice. The mod worked, but the screen isn't as bright as I was hoping it would be, and I'm wondering if it has to do with the way I installed it. I recently completed the GBC frontlight mod using a frontlight and Osaka 7 LOCA from Hand Held Legend.
