QSound requires its own firmware rom to work. The original board has a first-order low pass filter at 770 Hz, this can be implemented with a first order IIR filter: The OKI PCM input clock is 1MHz, depending on the SS input setting, this gives two sampling frequencies: SS Using the FPGA logic analyzer I could check that the period was indeed constant but hiss was present. That effect was not noticeable in MiSTer, which uses a different DAC.Įven with the right clock enable, there is still hiss occasionally in MiST(er). The effect of jitter is very obvious in the DAC used on MiST because when all sound goes silent an ugly transient occurs.

Otherwise the sampling period will not be constant, generating jitter. The DSP16A clock enable must be an exact multiple of 30MHz. This may be a problem with MRA file, and not with the core itself. Fuel hoses in Carrier Airwing appear on top of the airplane. A file will be created at the root of your SD card called game.RAM, where game will match the name of the. After you have configured the settings, save the contents using the OSD option Save NVRAM. You have to enter the test menu to configure it (via OSD). Pang! 3 and all CPS 1.5/2 games did not use DIP switches to configure the game, but a small non-volatile RAM. You can however flip the image through the OSD. Vertical games require you to turn your screen around. Note that there is no screen rotation in MiST. Important: make sure to have the latest firmware and latest version of the mra tool.Ĭopy the RBF. The three files must be in the root folder. Note that the RBF name must be JTCPS1.RBF for it to work. arc file can be used to start the core and directly load the game rom file. Basically call it like this:Īnd that will produce the. The rotate screen OSD option is ignored for horizontal games. It is also possible to keep the MAME romsets in _Arcade/mame but have the MRA files in _CPS and the RBF files in _CPS/cores Copy zipped MAME romsets to _Arcade/mame. Setup MiSTerĬopy the RBF file to _Arcade/cores and the MRA files to _Arcade. Note that if the option is enabled the 2P, 3P and 4P buttons will also activate the slow down effect. Release the 1P button to go back to normal speed or disable the option in the OSD. If you enable the 1P_hold_for_slow setting on the OSD, then while the 1P button is held the game will run at half the speed. There is an option to slow down the game (available only for CPS2). If there is still one button left in the gamepad, it will be used for pause. Press 1P during pause to toggle the credits on and offįor MiST, the first 6 gamepad buttons are used for game buttons, the next 2 buttons are used for credit and start buttons. However, the keyboard can be used with more or less the same layout as MAME for MiST(er) platforms. Those games are listed as having a GFX ROM of 16MB or more below. Some CPS2 games may require a 64MB module.

Memory RequirementsĪll CPS1 and CPS1.5 operate correctly on a 32MB SDRAM system. When playing in the future and you want to continue from your saved state, you can use File > Load State to load up the game from exactly where you last saved it.Capcom System 1/1.5/2 compatible verilog core for FPGA by Jose Tejada (jotego). You can save your progress in whatever point you like within the game, not only on the official checkpoints offered by the game. Instead, you’ll need to click File > Save State and then choose an empty slot. The integrated save system will not save your progress. Tip: Saving games on an emulator functions a little differently. The game will now run on the emulator and you can play the game freely. Step 2: return to Retroarch and hit File > Open. A ROM is essentially a virtual version of the game that needs to be loaded into the emulator. But now you’ll need to find the correct ROMs online. Your emulator will now be ready to play Metal Slug rom. After, double click the RetroArch-1.7.5-x86-setup.exe file in order to start the emulator.
