Version 1.2 emergency bugfix release

Changes:

• Fixed highlighted option in MSX2 mode (fixed stupid bug in my experimental VDP logic)
• Removed CTRL+STOP break (I left it enabled for testing now is stable enough so is not needed)
• Removed spanish texts in example descriptions in readme texts
• Reuploaded screenshots with sample options in english instead of spanish (ofc, you can use your own language)
• Now help screen cleans the whole screen before showing the text (much cleaner now)
• Some minor changes
• Minor preparations in main.asm code for new features
