Personally, I had a different experience and turn of events when I years back, maybe in 2012, wanted to replay Jak & Daxter after not touching it since when it came out. I like to keep my computer less cluttered than it can be and not fill it with drivers and new hardware, and use it for work, internet and development only.Ĭonsole just works, no nostalgia or retro reason here.Įdit: well, ok, not counting laser read issue here, because console is old or CD/DVD is dead. Yes, it already happened to me (it was a conflict with Unreal (first unreal game, not tournament)/BIOS version/mother card bus type/soundcard/specific config), I stopped trying to play on PC since then. Not even counting blue screens, reboots, freezes and losing work I had (unsaved generally) in other opened applications. you always need to setup and find proper drivers and get latest updates and fix conflicts, update directX (if possible), or update your entire OS version! and then you notice controller is not recognized, then you have to set each buttons and calibrate, and then each game has to be tweaked in the settings for better frame rate, frame skip, and GPU settings etc. Proponents of very high accuracy point to games that require such a high degree of accuracy in order to be fully playable, as well as the importance of preserving the historical experience and the intent of the designers. Cycle accuracy in particular has been hotly debated in regards to its usefulness, due to how such an extreme level of accuracy requires a lot of extra processing power for relatively few gains in compatibility. On most platforms, after obtaining a certain amount of accuracy, going further still requires an exponential growth in system requirements, the results of which may not be noticeable to the vast majority of users. Thus, speed and scalability to most devices takes a backseat to accuracy to the real console, both for purposes of compatibility and preservation.Įven within the second camp, however, there is some disagreement as to just how much accuracy is actually needed. The other side argues that an emulator should ultimately strive to simulate the hardware as much as possible, as that is the only way to achieve as much compatibility as possible, as well as the only way to preserve the hardware. The faithfulness of the emulator to the console it is emulating comes second to its overall ability to play games. One side argues that as long as an emulator plays the majority of games at full speed on most computers and devices without too many obvious glitches, it does not matter how accurately it actually replicates the original hardware and its many quirks and functions. There are basically two camps when it comes to the issue of accuracy. Such low level emulation requires a tremendous amount of power to run. ![]() The accuracy of these emulators are close to perfection, but at a steep CPU cost.Ĭircuit accurate emulators work by simulating each logic chip on the board individually. How much performance is taken depends on the way cycle accuracy is implemented and the skill of the coder. So each individual component is emulated at exactly the right time, and in perfect sync etc, which takes a performance hit. Some high accuracy emulators can achieve 100% compatibility with commercially released games.Ĭycle accurate emulation is basically trying to perfectly emulate timings right down to per-cycle accesses. High accuracy emulators may or may not be cycle accurate. They will have fewer audio and visual glitches. High accuracy emulators try to replicate the original system as closely as possible, and for that reason take more CPU power to do so. Medium accuracy emulators will have fewer glitches, but will still have many problems. This means that the romhack can only be used in that one specific emulator. This can become very problematic when ROM hacks use these speedhacks to run by abusing the errors to create otherwise impossible behaviour. They will typically use various speedhacks to skip over problems, as a result many games only run due to a variety of patches while others don't work at all. Low accuracy emulators will have a large amount of visual and audio glitches. ![]() There are hopes that less CPU power will be needed for more accuracy with the use of tighter programming. More accuracy means less graphics and audio glitches, at the cost of additional CPU power required to run the game at fullspeed. ![]() Accuracy is most often achieved by tighter syncing. Accuracy is how accurate the emulator is to the original hardware.
