open_agb_firm beta build 2024-07-30

What's Changed

• 5356e5c Implemented full gamma correction for top LCDs which improves colors noticeably without crushing details in shadows. Colors should no longer look too dark regardless of the colorProfile setting. Note that due to wildly varying color temperatures and LCD types this will not make GBA games look exactly like on your monitor with or without color correction. Also note that the gamma curve is not a perfect fit for IPS New 3DS XL consoles since they have very bad gamma near shadows but it's a very noticeable improvement nonetheless.
• A side effect of the new gamma correction is that the gbaGamma, lcdGamma, brightness and contrast settings are disabled for now. They will be reimplemented in the color profile settings later.

Example of what the gamma curve correction does. The brighter version is roughly how the top LCD shows colors without correction.
