Free DS Emulator: How to Speed Up

Are you tired of waiting for your favorite Nintendo DS games to load? Do you want to experience the thrill of playing Pokémon, Mario Kart, and other beloved titles without any lag? Look no further! In this article, we'll show you how to speed up DeSmuME, a popular free DS emulator for Mac.

Understanding RNG Manipulation

Before we dive into the speed-up techniques, it's essential to understand RNG (Random Number Generator) manipulation. In the context of DeSmuME, RNG refers to the way the emulator generates random numbers that affect gameplay. One crucial aspect of RNG is PIDRNG, which determines the nature of your starter Pokémon in Pokémon games.

IV Frame 11 vs. IV Frame 1

When running a speedrun, you can't select your starter Pokémon from IV frame 1 because it's not possible to set the clock and pick your starter simultaneously. Instead, you must go through the entire New Game sequence before selecting your starter. This means that your IVs will be selected from IV frame 11.

PIDRNG Frame Advancement

The PIDRNG is advanced by an inconsistent amount from its intended starting frame. This means that each seed has a fixed amount of PIDRNG advancement, but the amount is not consistent across seeds. PPRNG and RNG Reporter offer functions for searching stats on IV frame 11, but neither program accounts for the PIDRNG frame advancement caused by New Game.

Generating Seeds and Testing

To get the desired IVs, you'll need to generate seeds that give you the desired nature and then test them one by one until you find a seed that works. If you're running DeSmuME from your Mac, you can still perform RNG manipulation using the emulator's DS parameters.

DeSmuME Parameters

DeSmuME uses your system clock as the default DS clock. However, you can also use the 'Record Movie' feature to specify a fixed start time without changing your system clock. This is essential for achieving consistent results across multiple runs.

MAC Address and DeSmuME Version

The MAC address for all versions of DeSmuME is 00:09:Bf:12:34:56. The following table outlines the parameters for different combinations of DeSmuME version and game (all parameters are for English only):

| Game | DeSmuME Version | Parameters |

| --- | --- | --- |

| Pokémon | 0.9.11 | Timer0, MAC address 00:09:Bf:12:34:56 |

| Mario Kart | 0.9.10 | Timer0, MAC address 00:09:Bf:12:34:56 |

Speeding up DeSmuME on your Mac is possible by understanding RNG manipulation and using the emulator's DS parameters to achieve consistent results. By following these tips, you'll be able to enjoy your favorite Nintendo DS games without any lag or frustration.

Remember to always use the 'Record Movie' feature to specify a fixed start time and ensure that multiple runners can obtain the same starter Pokémon. With DeSmuME, the possibilities are endless!
