| 52 | 52 | - Improve alpha blending. In Viper Phase 1, see the blue "Viper" logo when on the |
| 53 | 53 | "push 1 or 2 players button" screen. Note that the alpha blended red logo on the |
| 54 | | title screen is tiles(that effect is emulated), this blue logo is sprites. |
| 54 | title screen is tiles(that effect is simulated), this blue logo is sprites. |
| 55 | 55 | The current implementation is a crude hack. |
| 56 | * DMA table? can't find any |
| 57 | * data in transparent pen? nope |
| 58 | * color bit 15? nope |
| 56 | 59 | - not sure if sprite priorities are completely right |
