The lower halves of 8x16 pixel sprites is drawn using the wrong tiles. (Potential off-by-one error)

Why are the sizes for ROM[0x0419] codes 0x04 and 0x05 flipped in Hardware/Cartridge.cs? Is this weirdness in the actual GameBoy hardware, or just an error in your code?

Currently, displaying sprites doesn't work properly when their X coordinate value is below 8.

Object sprites aren't loaded/shown at any point in the game.

Under some circumstances the dialog boxes contain seemingly random tiles between the lines of text.

When starting the game, a copyright notice screen should pop up and stay for a while, before fading to the Titus logo animation. The screen only pops up for a very short amount of time.

When playing Link's Awakening the bottom row of pixels should show the currently equipped items, health and rupees, but instead shows scrambled overworld tiles. Pressing START to open the menu keeps displaying the normal overworld with the selection cursor shown on top.

Note: Possibly related to sprite-drawing and windows.

After defeating the boss in world 1-3 the sequence plays where an enemy reveals its Princess Daisy disguise and jumps around. Sadly, this jumping continues on indefinitely, softlocking the game.

After starting a new game and having the first intro sequence played the game resets to the opening sequence and loads back into the main menu.

As of 0f873dd, after the first intro sequence has played the game gets stuck on a blank screen.

When playing Super Mario Land, the labels for lives, score, etc. tend to flicker. Also, the bottom pixel row of the label section is often affected by background scrolling, although it shouldn't be.

When starting the game the LCD stays off and no further action is taken.

While MBC3 does save the external RAM to a save file, it does not contain the save data of the game. Possibly related to RAM-addressing.

When closing the emulator the MBC3 clock doesn't preserve its data when the cartridge should contain a battery.

When playing Dr. Mario the music is mostly silent, except for "backing" music played on the secondary channel.

Under unknown circumstances the game softlocks when attempting to enter a pipe.

Sounds that supposedly should use the volume envelope either stay at a constant volume or are muted entirely.

While near the starting area of the game Samus is invisible, yet controls still work as intended. Samus' sprite is displayed starting at a certain distance from the ship and doesn't disappear afterwards either.

The PPU locks the OAM and VRAM memory sections before it should, making games not clear up tiles on scene changes and similar.

After defeating the boss in World 2-3 the game gets softlocked in a similar fashion to the previous issue with the World 1-3 boss.

Any "large" sprites (characters in battle animations, pokemon, etc.) are shown as black squares.

While playing the level World 2-3 the game often gets stuck with scrolling until a certain coin is collected. This is probably related to sprite drawing timings of the PPU.
