* SJ: Fixed colours based on screen shots, they're probably OK,  *
*     but more shots would be good for verification              *

* MG: Dave seems to think that the AY is hooked up wrong since   *
*     it generates lots of errors in error.log, even though the  *
*     sound seems to make sense. Can someone with a PCB stomach  *
*     the game long enough to verify one way or the other?       *

* Super Trivia has some really weird protection on  *
* its question data. For some odd reason, the data  *
* itself is stored normally. Just load the ROMs up  *
* in a hex editor and OR everything with 0x40 to    *
* get normal text. However, the game itself expects *
* different data than what the question ROMs        *
* contain. Here is some pseudocode for what the     *
* game does for each character:                     *

*     Invert A               // Invert the bits     *
*     AND A,$1F              // Put low 5 bits of   *
*     B = Low 8 bits of addy // addy into high 8    *
*     C = 0                  // bits of BC pair     *
*     Call ArcaneFormula(BC) // Get XOR value       *
*     XOR A,C                // Apply it            *
*     Return                                        *
*                                                   *
*     ArcaneFormula(BC):                            *
*     ShiftR BC,1                                   *

*                                                   *
* Essentially what ArcaneFormula does is to "fill   *
* out" an entire 8 bit number from only five bits.  *
* The way it does this is by putting bit 0 of the 5 *
* bits into bit 0 of the 8 bits, putting bit 1 into *
* bits 1 and 2, bit 2 into bits 3 and 4, bit 3 into *
* bits 5 and 6, and finally, bit 4 into bit         *
* position 7 of the 8-bit number. For example, for  *
* a value of FA, these would be the steps to get    *
* the XOR value:                                    *
*                                                   *
*                                 Address  XOR val  *
*     1: Take original number     11111010 00000000 *
*     2: XOR with 0x1F            00011010 00000000 *
*     3: Put bit 0 in bit 0       0001101- 00000000 *
*     4: Double bit 1 in bits 1,2 000110-0 00000110 *
*     5: Double bit 2 in bits 3,4 00011-10 00000110 *
*     6: Double bit 3 in bits 5,6 0001-010 01100110 *
*     7: Put bit 4 in bit 7       000-1010 11100110 *
*                                                   *
* Since XOR operations are symmetrical, to make the *
* game end up receiving the correct value one only  *
* needs to invert the value and XOR it with the     *
* value derived from its address. The game will     *
* then de-invert the value when it tries to invert  *
* it, re-OR the value when it tries to XOR it, and  *
* we wind up with nice, working questions. If       *
* anyone can figure out a way to simplify the       *
* formula I'm using, PLEASE DO SO!                  *
