Implement much better test case for decimal mode. 2017-02-11 22:36:57 +01:00			`; somewhat inspired by http://www.6502.org/tutorials/decimal_mode.html`
Premilinary support for decimal mode. While here add SED emulation. Implement BCD support for ADC instruction. 2017-02-10 22:23:06 +01:00			`start: sed`
