If something like the eeprom test is wrong, who knows what else can be affected ? What if in fact, the CPS1 SF2 games actually ran at 10 mhz (instead of the 7-8 mhz that is “proper” for accurate play in SF2:HF), but whatever is causing the EEPROM speedup, is also somehow affecting the throttling code, and possibly forcing a SLOWER cpu ?Ħ8k bug? Some unemulated code that needs to be looked into? Now, before I get flamed for posting something insignificant, WHY DOES CALLUS HAVE THIS SPEED ARCADE PERFECT? And, isn’t the goal of emulation to have everything accurately emulated 100% ? Even setting the CPU to 60% (slower than a real machine) has the test run too fast. Setting the CPU to 65% (which results in arcade perfect speed–remember folks, SF2:HF plays too fast at anything higher than 8 mhz) in SF2: turbo hyper fighting, still does not fix the EEPROM test. There is something more that MAMEDEV needs to note here. (I have no idea whether this occurs in the arcade machine–how many people have seen an overclocked PCB? Overclocking the CPU and resetting the game in the emulator makes the EEPROM initialization go even faster.
So take that with a grain of salt.Īnother thing worth careful noting, is that this EEPROM initialization is closely tied in to the CPU speed of the game, even if the throttling is disabled (SF2:WW, CE). The CPS2 resets are taken from “memory”, as I have only seen a CPS2 reset from power off a few times. Note: the EEPROM RESET speed is identical in WW, CE, and HF.Įven the CPS2 eeprom resets are too fast, but I have only verified this with CPS1 eeprom reset initializations. I have reset the arcade machine many times (mainly, to see which revision I was playing :>), so I am familiar with the speed of the test scrolling. The callus initialization is arcade exact. This occurs on any emulator that shares a similar CPU core (MAME, Finalburn, Kawaks). In the SF2 games, the EEPROM (power on initialization) test is too fast. For example, while the Super Nintendo version plays almost like in the arcade, it has different graphics, different sound effects etc. Is there any arcade perfect port of the original “Street Fighter II - The World Warrior” (not “Champion Edition” or “Hyper Fighting”) on any system (not counting MAME)?
