BUGFIXED VERSION OF "MANIC MINER MYTHOLOGIES: EUGENE - LORD OF THE BATHROOM"
 
"Manic Miner Mythologies: Eugene - Lord of the Bathroom" is a 1999 game by Vidar Eriksen (Erix1). The original release of the game suffers from a bug which prevents the player from seeing the title screen and the scrolling message by starting the game immediately without waiting for the player to press ENTER.

This happens because at #8636-#8638, there is a conditional jump (a JP NZ instruction) to start the game if the ENTER or fire button was pressed. This would have been checked for by the 'Play the theme tune' subroutine, but the call to that particular subroutine, in the original "Manic Miner" located at #8633-#8635, is NOPped out in "Manic Miner Mythologies: Eugene - Lord of the Bathroom". As a result, if the Zero flag is not set when that point is reached in flow of execution, then the jump is activated and so the game will start automatically. This does not happen only if a Kempston joystick is connected (because a check for whether the joystick is connected is just prior to the conditional jump to the start of the game, at #8626-#862E - the Zero flag is set if the joystick is present and a variable related to it is initialised).

The issue was raised publicly in March 2023 on the Jet Set Willy & Manic Miner Community forum. Ian Rushforth (IRF) immediately proposed a solution (which he had actually privately arrived at back in 2019), which involves inserting an XOR A ('AF') instruction at #8633. It has the effect of setting the Zero flag, so the condition to activate the subsequent jump is not met and the game does not automatically begin. 

This bugfixed version has been prepared according to Ian's solution, without any other changes in relation to Vidar's original TAP file. Vidar kindly endorsed it in March 2023, making it the official bugfixed version of "Manic Miner Mythologies: Eugene - Lord of the Bathroom".

Thus, this ZIP file contains bugfixed, problem-free, original-author-approved version of "Manic Miner Mythologies: Eugene - Lord of the Bathroom" in TAP and TZX format.
