… hardware and needed to rework it. The end of the day finally pays off, enjoy world’s first premiere: Super Mario Land on Watara SuperVision!

[elefas @elefasgr]

World is not ready for this! #SuperMarioLand running on original #Watara #SuperVision hardware!

ROM flashed to stubborn SuperPico took me more than one day to make it work, I gutted my supervision since SuperPico needs to be powered on (usb) before inserted to SuperVision …

… else it doesn’t boot. Helpfully supervision can be powered from cart lines so usb powers both SuperPico and SuoerVision! Hot inserting the cart made it boot! After this first breakthrough, the scrolling mechanism that was working fine in the emulator was broken on real…

@CaptainN_DK Well I plan for 1:1 port, at least to the extent supervision capabilities allow. Your suggestion for the last row tiles is interesting, i wonder if supervision has enough “oomph” to implement it, i note it down in my todos.

#SuperMarioLand for #Watara #SuperVision, World 1-3 completed. King Totomesu defeated and Mario finally meets Daisy... oh no! #RetroDev

[elefas @elefasgr]

@kovdaniel_ @CaptainN_DK thanks!

[elefas @elefasgr]

@CaptainN_DK Scrolling-wise it should be much much better than any released supervision title. That was my initial intention starting the port.

I am waiting for a superpico flash cart to arrive to test in on real hardware, so far only in emulator. Let’s hope it works!

[elefas @elefasgr]

@CaptainN_DK Imagine if back in the days such tech demo existed for watara supervision or a third party developer ported a famous title to it keeping it as much faithful to the original gameboy title. It would make the console sell like hot cakes.

Full steam ahead for world 2!

@CaptainN_DK Spotted a missing mushroom ;P

@CaptainN_DK Thank you my friend!

[elefas @elefasgr]

World 1-1 complete! #SuperMarioLand port for #Watara #Supervision proves impossible is nothing! Enjoy #Supervision sound circuit chirping the iconic and most recognizable #GameBoy tune!

p.s. recording in Mac worsens the sound quality.

Stomping Goombos in #SuperMarioLand port for #Watara #Supervision! Next in queue? Bombshell Koopas and the Flies.

- Bonus stage? - Implemented too!

First level near completion. Next big task? Sound/Music! Let's see how much power #SuperVision has! #RetroDev

scrolling is done by hardware XSCROLL plus a DMA buffer-shift and per-column streaming, and the GB's planar tiles, level segments, jump-arc and object/AI tables are all converted out of the ROM at build time.

Eating shrooms and butter smooth scrolling for this #SuperMarioLand port for #Watara #SuperVision!

Runs on the Supervision's 65C02 with no sprite/tile hardware — Mario and everything else are composited into a 2bpp linear framebuffer (4px/byte) in software,
