Sonic Mega Collection (ソニック メガコレクション 'Sonikku Mega Korekushon) is a video game compilation of Sonic the Hedgehog titles for the Nintendo GameCube It includes seven Sonic titles, all of the Sonic & Knuckles expansions/combinations, two bonus unlockable games, and a wide selection of bonus material.

Games list:

Emulation Information

Improper GameCube Font

Due to copyright concerns Dolphin is unable to include official GameCube fonts, and instead uses "Droid Sans". Unfortunately Droid Sans does not align well with the size/kerning of the official GameCube font, which can cause text to be misplaced, dialogs to display improperly, and other issues due to augmented text sizes. This can be corrected by including a region appropriate GameCube IPL under <Dolphin User Folder>/GC/. A GameCube "IPL.bin" can be acquired from a real GameCube using Swiss. Refer issue 8362.

Problems

Sound Desync

Due to a flaw in Dolphin's handling of the GameCube sample-rate, audio will slowly desync in this game. There is no solution currently. See issue 9235.

Frame Issues in Blue Sphere Game

When the game lags, it is possible that it will duplicate or show the wrong frames in the wrong order. This is most evident in Blue Sphere, where it will happen when there are any number of spheres on the screen. In order to avoid this, enable "Emulated CPU Clock Override" and set it to 150% or higher. Refer issue 7199.

Various Minor Graphical Issues

While playing through the 2D Sonic games, some visual oddities may be seen, for example: spikes spawning in out of nowhere, certain objects not rendering right away, or flickering on the Act 1/2/3 text. To fix these issues, set Texture Cache Accuracy to Position 1 (Safe), however this can cause reduced performance.

Enhancements

The following codes adjust the horizontal FOV for widescreen support, but these are only for the 3D menus.

5.0-381 Windows 10 Intel Core i5-3570K @ 3.4GHz NVIDIA GeForce GTX 1070 The game works perfectly if you're willing to overclock the emulated CPU. If not, it's only merely playable. JMC4789
