Ived used kawa patch to add SVC and Metal Slug 5. SVC works fine. When running MS5 can see credits and the rest of the screen is black with white dots. When i hit back to put in coins it looks normal then when i hit start the sound is repeating fast and theres like little boxes with some colors but it changes every 2-5 secs u cant see anything that looks like a game. Does anyone know the fix for this prob as its doing my head in. thanks very much.
