Emu64 is a low-level emulation program, which emulates the Commodore 64 on a PC running Windows. Usually it is desireable to limit the freedom of window scaling and enforce that the window's width and height are always scaled with by same factor. C64 Palette: There are many different opinions, based on the observation of different C64s connected to different TVs and monitors, what the 16 C64 colors look like and how they should be displayed on a Macintosh.
It is also possible to use a customised palette. To do so, first select the palette that is already closest to your desired palette, and then select 'Palette Editor' from the pop-up menu. Starting out from the previously selected palette you can now fine tune the colors to match the colors on your Mac screen to those of the original C Use Color on Color Screens: Power64 can display the C64 screen in original colors or as a black and white image. Enabling this option is definitely recommended. Zoom Out Cmd - : Reduce the zoom factor of the current C64 window by one. Use the Option key to make the new size apply to all open windows.
Invisible Background Cmd-I : Power64 is a well-behaved Macintosh application, that runs in regular windows. Outside the Power64 windows the Finder and other applications' windows are visible. To create a more Clike feeling Power64 has the ability to draw a big black window over the entire screen, that hides all other applications. If you also want to hide the menu bar check "Hide Menubar for Black Frame" above. Sound Sample Rate and Sample Size control the sound quality for immediate playback.
Higher sample rates produce better sounds, but also create more Mac CPU load. Any extra samples created by Power64 will be discarded by the Sound Manager, missing sample will be interpolated at additional CPU cost. In addition to this you should make sure that the sample rate for MIDI playback is configured to at most Hz. This value is sometimes changes by external audio interface like the Griffin iMic or other USB audio interfaces or their drivers that remain in the system even after the hardware has been unplugged!
You should check that the setting is correct both with the hardware plugged in and unplugged.
This is not a Power64 specific problem. Other applications like Quicktime suffer from the same problem. Power64 will always create Samples in 16 bit. The 8 bit option simply discards the least significant 8 bit. This does NOT save time or space, and is intended only for estimating the achievable quality of a 8 bit recording. Sound is played back at at most Hz by Power Selecting a higher sample rate will not cause playback at that rate which would furthermore not be possible using the Apple Sound Manager.
Instead Power64 computes the samples at the chosen samplerate and then averages two Hz or four Hz of these oversamples to create a sample usable for playback at Hz. To hear or record the melody played by a single voice clearer Power64 can selectively mute single voices.
Activate Filter: Before sending the sound of the three SID voices to the speaker it can be sent through a common filter to modify the sound. On a real C64 the filter is always present.
Software development never really stopped. There are many tools available today.
In Power64 the filter is optional. If active it does consume some extra CPU power, but reproduces the sound of the C64 better. Sound Recording: Power64 also offers the possibility to record the sound played by C64 games to a AIFF sound file that can be played e. Furthermore Power64 can record sound in reSID file format. This file format requires much less hard disk space than AIFF, because not the actual sound samples are recorded but just the commands sent to the SID sound chip.
This is recommended unless you want to analyze the contents of the file by hand or some other program. Power64 also supports the Frodo file format, but this is done only for reasons of compatibility to older versions of Frodo. Frodo will soon switch to the reSID file format too, so that this file format will fade out. These settings are not available when recording in reSID or Frodo file format.
High sampling rate and large sample size give good quality, but unfortunately also large sound files. It is not advisable to select a high Recording Sample Rate than Sound Sample Rate, because the extra samples are added by duplication of the computed samples.
Thus the 'useful' sample rate of the recording is just that of the Sound Sample Rate, while the disk space occupied will correspond to the higher Recording Sample Rate, combining the disadvantages of both high and low sample rates. Pause Recording during Silence: Power64 can automatically stop sound recording when there is not tune to record.
Enabling this feature causes Power64 to delay any recording until the music starts and eliminate silence after the end of the music. This is a very useful feature as you can start the recording before running the game without causing useless stretches of silence in the AIFF file.
Unfortunately some games produce sound with lots of intermissions, that sound queer if these intermissions are truncated. For such games it is useful to turn off the Pause Recording feature. Click on Select Sound File Folder to choose the folder in which these files are to be stored. As the SID emulator requires a significant amount of processing time, turning off the sound will give a performance boost to games that would otherwise be to slow to run at full speed. Decreasing the volume when it is already at its minimum, will disable sound emulation.
Increasing the volume again will turn it back on.
Pressing the Option key while selecting a new mode for the SID emulation will cause all open Power64 windows to adopt this mode. The sounds will be recorded at the sample rate and size chosen in the Sound Options dialog to a file called ' C64 Sound - dd. Power64 supports two keyboard modes - Macintosh Keyboard mode and C64 Keyboard mapping.
Usually this effects only the active emulator window. If the Option Key is pressed when selecting a new Keyboard mode, than this mode is activated in all emulators. In Macintosh Keyboard mode the translation between pressed Macintosh keys and logical C64 keys is based on the character that is usually associated with a particular key. This is very handy if you have not used your C64 very much recently and are no longer familiar with its keyboard layout.
