(01/20進度,已經把sprite顯示上去了)gameboy在1989年發售,
任天堂紅白機在1983年發售,原本以為紅白機因為發售得早六年,結構應該比較簡單,
比較好開發,也的確是相比之下硬體規格是簡化不少,但實際撰寫來說,
我覺得紅白機難度比gameboy還高不少,最主要是就是因為規格簡化不少,
很多地方的處理變得有很多奇奇怪怪的規則,特別是cpu透過reg對ppu記憶體的讀寫處理,
搞不太懂(應該是說還得花時間去k),還有夠詭異的畫面輸出運作週期規則,
那會影響到vram讀寫的位址偏移...結果功能簡單了,但規則反來覆雜不少,
更別提一卡車的遊戲卡帶mapper規則(雖然我也只想支援主要幾個),
目前跑起來好像還有一個樣子的遊戲大多數都是非常簡單的,
而且也不是完整處理正確,只能說自己還有太多不足的地方.
沒辦法到達一定完整度的話,等於白寫,反正就當學習,看緣份吧...
總之未必能順利到最後發佈階段就是.
