* Thanks to MooglyGuy for working out why statriv2 was crashing  *
* in attract and fixing the questions so it actually asked more  *
* than one per category.                                         *
*                                                                *
* Game Speed too fast?                                           *

* 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?       *
*                                                                *
* RF: Reworked the Status Fun Casino inputs. Lowered the CPU     *
*     clock to get it working properly. Added technical notes.   *

    *                                                   *
    * 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:                     *
    *                                                   *
    *     GetCharacter:                                 *
    *     In A,($28)             // Read character in   *
    *     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                                   *
    *     DblShiftR BC,1                                *
    *     DblShiftR BC,1                                *
    *     DblShiftR BC,1                                *
    *     ShiftR BC,1                                   *
    *     Return                                        *
    *                                                   *
    * 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: AND 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!                  *
