The CPU governor controls when your overclock is applied. Overclocking arm_freq may benefit pi 1, 2 and zero models for some N64 games but offers no benefits for the pi3b or pi3b+. Though it may help increase performance for other high CPU usage emulators such as PSX or MAME. There was no discernible FPS increase overclocking the Pi 3b's CPU from the standard 1200mhz to 1350mhz. Most of the raspberry pis I tested were stable to at least v3d_freq=500 but not much past this.Īrm_freq(CPU) overclocking is of little to no help for boosting N64 performance on a pi3. This helped improve performance for a couple games I tested. Sdram has its own over voltage value over_voltage_sdram. Going from 450mhz to 550mhz yielded at best about a 1FPS increase. Overclocking sdram_freq will give a very small boost to performance. If your pi freezes or crashes then your overclock is unstable. You will need to experiment to see how much your pi can handle. Again, it is important to remember that not all pis are equal, some will only overclock a little or not at all. Most pis I tested were stable between core_freq=500 and core_freq=575 with some amount of over_voltage applied. Therefore before you begin overclocking please review this article first for proper overclocking methods and stability testing to prevent SD card corruption and potential loss of your data.įor boosting N64 performance, it is the core_freq(GPU core) setting that will give the most benefit. There are no standard settings for overclocking and not all pis will handle the same amount of overclocking. It can add instability if not done properly. Overclocking is setting a hardware component to run faster than originally intended by the manufacturer. Setting the overclock bit can void your warranty. The specific circumstances where the overclock bit is set are if force_turbo is set to 1 AND any of the over_voltage_* options are set to a value > 0. NOTE Setting any overclocking parameters to values other than those used by raspi-config may set a permanent bit within the SoC, making it possible to detect that your Pi has been overclocked. Back up your image before attempting to overclock. An unstable overclock will lead to freezing, crashing and SD card corruption. Overclocking should only be attempted by advanced users who understand the risks. Hardware and ConfigurationĪ Raspberry Pi 3 or later model is highly suggested to maximize performance. However, listed below are several tweaks that can be made to your raspberry pi that will help maximize N64 performance and make many of the popular N64 titles playable. a desktop computer, modern mobile phone/tablet etc.). If you are looking for a more perfect N64 emulation experience you should seriously consider different hardware first (i.e. N64 emulation on the raspberry pi is difficult due to the pi's under powered GPU (Graphics Processing Unit) and lack of certain GPU features found in more modern devices.

Since video game smoke of this era was often depicted with black garbage pixels, the mistake went unnoticed for over two decades. It’s now known that this texture is displayed in the wrong format by the game, resulting in black garbage pixels. According to hacker zoinknoise, they simply changed “G_IM_FMT_RGBA” to “G_IM_FMT_IA” on line 47 of the “/actors/burn_smoke/” file. The much better looking smoke particle was inside the game all along, hidden beneath an incorrect line of code. And modders fixed it in only a single line of code.Īccording to the patch’s description on, the hack adds no new art. Super Mario 64’s smoke effect, emanating from the plumber’s toasted hindquarters, always looked a bit silly - even for the Nintendo 64.Ī new ROM hack for Super Mario 64 reveals a fix for what we now know was a visual bug. Players have been roasting poor Mario’s buns in lava pits since the days of Super Mario 64, and everyone can remember Mario’s cries of pain as he leaped out of the burning pools.
